Footwell Lighting:

J.A.'s Footwell Lighting Schematic

Factory (unmodified)
Interior Light Schematic
 
Concept:
This modification adds much needed front and rear footwell lighting on a 4th generation 2007 Toyota 4Runner. Led (light emitting diode) type lighting will be used. These lights will be wired to automatically turn on when any door is unlocked using a key or keyless transmitter, or if any door is opened.
 
The standard feature that shuts off the factory dome lighting system after 30 minutes of being inadvertently left on will be used in conjunction with this mod to prevent excess battery drain. The footwells will fade in and out just as the factory dome lights do.
 
Additionally a three position switch will be added so that this mod can be set to automatic mode, turned on "on demand", or be switched off. The off position of the switch will come in handy when working on the vehicle for long periods of time while repeatedly opening and closing the door, which will reset the 30 minute automatic dome relay power off feature. The on position will come in handy at night to turn on only the footwell lighting while the vehicle is in motion.
 
What needs to be accomplished:
For the footwell lights to come on automatically when opening the doors, this mod requires that the Body Electronic Control Unit's (ECU) Interior Light Enable (ILE) circuit be brought to the negative side of the footwell lights. For the footwell lights to shut off automatically after being left on for more than 30 minutes with the vehicle off, requires the positive side of the footwell lights to be powered from the factory dome relay circuit.
 
First we will disassemble some interior trim pieces to gain access to areas in which we will run wiring.
 
Remove driver side lower finish panel for access to driver side interior relay/junction box.
Start out by disassembling the lower dash area as we need access to the driver side interior relay/junction box. To access this area, first remove the two 10mm bolts holding the lower finish panel on. Pull the panel straight out to disengage 4 plastic clips still holding it on. The trim ring around the key hole will just pop out on it's own as you are doing this. Remove the wire harnesses attached to each of the switches located on the back side of this panel. Also on the back right side of this lower finish panel is the room temperature sensor harness (cooler thermistor), detach this from the panel as well. You may leave the fuel door release and the hood release handles attached to the panel. The panel can be lowered to the floor now.

Center Console Removal.
To remove the center console, start by removing the shifter cover. It is held on with five clips and two claws. To remove you simply pull straight up and back towards the rear of the vehicle. Before you can set the shift cover aside you need to remove any wire harnesses attached to it. In my case I had to remove the DAC switch wiring and the 12v power point wiring. You may have more if you have the seat heaters, rear air suspension or cigarette lighter options.

Next the console cover gets removed, this time there are 6 clips and two claws. To remove, again, pull straight up and back towards the rear of the vehicle.

Before you can lift out the center console itself, you need to remove the upper panel side garnish. To remove, unclip the side covers just in front of and below the cupholders. Then slide rearward to remove.

Tap into the factory Interior Light Enable (ILE) 12V- circuit.
I am going to tap into the ILE circuit on the back of the driver side interior relay/junction box, instrument panel wire harness connector 1K, Pin #9, red with green stripe wire.
 
I tapped into the ILE wire using a Red 3M Scotchlok 558 Electrical IDC (insulation displacement connection) connector which is perfect for 22-16 AWG solid or stranded wire. The ILE wire appears to be, in my estimation, 20awg. Run your wire from here up to where you will mount the dash switch. This will serve as your 12V negative wire for the led lights.

This would be the driver side footwell area. This wire will serve as your 12V positive wire for the led underdash and underseat footwell lighting.

Switch information and installation.
As mentioned earlier, a switch will be added so that this mod can be set to either of three modes. 1) DOOR (Automatic) Mode, 2) OFF, 3) ON.
 
While a SPDT (single pole double throw) 12V on-off-on switch will accomplish this, I chose to go with a DPDT (double pole double throw) switch. It is not necessary to buy this type of switch, and furthermore it will be wired up initially to use only one of the two poles.
 
The benefit of going with a dual pole dual throw type switch is that in the future, when I need to free up a factory switch blank on the dash for another mod, I can remove my Maplight mod SPDT switch and relocate the wires on it to the unused pole on my DPDT footwell mod switch thereby efficiently using only one switch for both mods.

    Switch Labeling.
    The Cole Hersee 58027-07 switch that I chose to use has a blank front which is perfect for a custom labeling job.
     
    I purchased a set of Woodland Scenics Dry Transfer Decals MG721 White Gothic Letters. To protect it I went with Testors Dullcote 3oz Spray Can TES1260. To layout the lettering as straight and centered as possible, I used some leftover 25 year old pinstriping I had laying around from my 1984 Oldsmobile Cutlass Calais project.

    Switch mounting.
    The Cole Hersee 58027-07 switch that I chose to use fits perfectly in the instrument cluster finish panel (upper dash) cutouts with no modification or trimming necessary to either the switch or the panel. Though the switch does not snap lock into place due to the thickness of the panel, the fit on the sides is more than tight enough to hold it in place.

    Switches mounted in dash

    A look from the back

    Switch wiring.
    At this point we have already ran one wire to the switch location. This wire was from the ILE circuit. I crimped onto the end of this wire, a 3M Nylon Fully Insulated Female Disconnect with insulation grip interlock barrel. These disconnects fit quite tightly onto the switch prongs which is why I prefer the type that have a insulation grip interlock barrel. These type of connectors require a double crimping method, the first to secure the copper wire, the second on the wires insulation which further secures the wire. This helps to hold the wire securely in place when you need to pull on the disconnect to remove it from the switch, which can be at times difficult to remove. A dab of dielectric grease on the switch prong will help in any removal efforts as well.
     
    Connect this ILE wire to the bottom prong on the switch.
     
    Connect another wire to the center prong on the switch, again using a female quick disconnect. Run this wire from here directly to the area in which you will mount the first of the four footwell lights. This area would be the driver side footwell location. Again, this wire will serve as your 12V negative wire for the led lighting.
     
    Now for the third and final wire to go to the switch. Using a 5" piece of wire (the black wire in my pics), use a ring terminal on one end and a quick disconnect on the other. Screw the ring terminal end to the screw that holds the driver side air vent to the dash reinforcement bar, this provides a constant ground source. Connect the other end to the upper switch prong.
     
    The switch is now wired to work as follows:
    Up Position: Footwell lights turn on instantly "on demand" (switch prongs 2-1 connected together).
    Center Position: Footwell Lighting Mod Off.
    Down Position: Footwell lights turn on (with fade feature) automatically when any door is either unlocked by a key or keyless transmitter, or if any door is opened (switch prongs 2-3 connected together).

    Switches installed

    Rheostat relocation.
    In the pics above, the switch on the left is for my Footwell lighting mod and the switch on the right is for the this Maplight modification. Since the factory rheostat switch went in the cutout on the left you may be wondering what happened to it. I relocated it to the area inside the fuse box located in the driver side lower finish panel. The factory wiring reaches there with no extension needed. I have never used the rheostat (dash light dimmer switch) on this vehicle or any other vehicle for that matter. I have driven a few road trips thru the night (8 hours of darkness) and never felt the need to dim the dashboard lights whatsoever. So relocating the switch to an inconvenient area to use was well worth the dash slot that was freed up.

    Rheostat relocated

    Running wires to underdash and underseat footwell lighting locations.
    At this point we have a white wire and a red wire exiting the drivers side lower dash area. To reiterate, the white wire is the 12V negative source which started from the ILE circuit, went up to the switch, and back down to the underdash location. The red wire is the 12V positive source and originated from the dome light circuit located on the back side of the driver side interior relay/junction box.
     
    We can now start to run a similar two wire bundle from this driver side underdash location, to the passenger side under dash area, and the underside of the driver and passenger side front seats. To keep things neat and organized, I like to tape the two wires together every six inches or so using black electrical tape.
     
    Running wires from the driver side footwell to the passenger side footwell is simple once you have both sides of the center console side garnish removed. There is plenty of space to pass the wire thru with ease. Leave enough slack at both the driver side and passenger side footwell areas to make connecting the wires to the light easy and also to enable dropping the lower finish panels down to the floor in the future.
     
    For the rear footwell lights, start by running only one set of wires from the driver side footwell area underneath the carpeting to the rear of the center console. Once there you can make a splice and run an individual set of wires under the carpeting to each of the two underseat areas. Again, leave enough slack in the wires to make the connection to the lights and to facilitate moving the seats within their full range of motion.

    Light Selection.
    The switch and wiring are in place now. Let's discuss the Led lights that have been chosen to be used for this project.
     
    At first, I gave much thought to using Flexible Led Strips such as those offered by V-Leds or Oznium. I decided against them as there is no ideal location to easily mount a full 12" Led strip where they can be tucked completely out of sight so as to not be seen directly while entering the vehicle, and not interfere with any surrounding parts.
     
    Next choice was the small form factor Straight 6-Led Modules offered by Oznium. I ultimately decided against these as the retailer could not give a quote on the approximate lumens that would be produced. My approximation is in the 20 lumen or less range and therefore at least two modules would be needed per footwell. This would create additional wiring as well as increase the cost of the project.
     
    Led technology is rapidly advancing and while in communication with one retailer, V-Leds.com, I was made aware of two new products that were not yet listed on their website. One was a 30mm x 30mm ultra thin led circuit board with self adhesive backing made up of 9 high power surface mount (SMT) Leds. The other was an even smaller and even brighter 6 high power M-SMT led board sized at 16mm x 16mm x 6mm. The 9-Led board would run at about 1.5 watts and put out approximately 60 lumens. The 6-Led board would run at 3.0 watts and put out about 120 lumens.
     
    I liked 6-Led board for its very small size and thought these may be ideal for the limited space underneath the rear seats. The rear seats on the 4th gen Toyota 4Runner really don't have much room underneath them especially on the driver side which has a power adjustable height feature which I keep set to near the lowest position. Though they do not come with a self adhesive backing, the 6-Led board's back is flat/smooth and double sided tape can be applied at the time of installation. I also liked the 9-led boards for their lower power consumption as I was a little worried that the 6-Led boards may generate higher heat levels and that their 120 lumen rating may be a bit bright for this application. So I figured I would order both, try them and return the ones I did not like.

    Testing.
    I will detail what I know and have learned about each particular Leds specifications. I feel that it is important to be informed of and understand this info in order make the right choice for a particular application. You will find that there are a vast array of 12V Led replacement automotive light bulbs on the market from a wide variety of companies. For example, for a common incandescent #194 5W bulb there can be literally over 100 different Led replacement choices from various companies, in various color ranges, running at various power levels, providing vastly different light output, and of course at various price points.
     
    Unfortunately not many retailers make these specs available or provide consistent information on their websites. In fact upon contacting a few of the companies myself, they simply either don't know, don't care to find out, or don't want to share that type of info. This makes it hard to comparison shop amongst various competing products. Specs such as "high power", "HID color", "cool white", "super bright", etc., really are meaningless without tested numbers to substantiate the claim. As with any product, you have to take the manufacturers or retailers advertised information with a grain of salt, do your own research beforehand, and follow it up with independent testing.
     
    While I am unable to test the Color Temperature or Luminous Flux ratings due to not having access to that type of testing equipment, I can confirm the advertised Watts (power) and Amps (current draw). To do this one can use a simple electrical multimeter which can test the current draw and supply voltages. Multimeters cannot calculate wattage, but you can back into the number by multiplying the supply voltage by the amperage draw of the electrical load.
     
    Before we discuss how to do this testing, let's discuss why. My goal is to add four high power Led footwell lights to the existing factory dome light circuit. This is being done, rather than running a new independent circuit, to tap into that particular circuits factory features (on with remote/key/door operation, off automatically after 30 minutes). No additional relays or fuses will be added to keep the wiring simple and neat. As long as we don't exceed the factory amperage draw for the dome light circuit, these additional relays and fuses will not be necessary at all and things will still be completely safe.
     
    I am changing out all the factory incandescent interior courtesy lighting to Leds at the same time as performing the footwell lighting mod. Since Leds run at a lower power consumption per lumen than incandescent lights do, the savings in watts seen by switching the interior courtesy lighting over to Leds can be used for the footwell lights in a safe and effective manor.
     
    To measure the DC supply voltage of the vehicle's battery, set the meter to volts, and connect the electrical multimeter in parallel with the battery.

    Vehicle off

    Vehicle on

    To measure the DC current draw of an electrical load such as an automotive light bulb weather it be incandescent or Led, connect the multimeter, operating as an ammeter in this case, in series (in-line) with the circuit so that all electrons flowing through the circuit have to go through the meter.
     
    When a multimeter is placed in ammeter mode, it acts like a simple length of wire, with very little resistance from one test probe to the other. Consequently, an ammeter will act as a short circuit if placed in parallel (across the terminals of) a substantial source of voltage such as the vehicle's battery. So be very sure to switch the mode from amps back to volts before connecting it in line (parallel) with the battery as if you don't you will create a short circuit. Hopefully your meter has a fuse, which will blow in that situation. If your meter does not have a fuse you will either damage your meter or your vehicle's electrical system.

    Measuring current draw (amperage)
    of the factory dome light

    Referencing the pics above, let's go thru a basic example checking the wattage of the factory festoon 31mm dome lights (DE3175) which are known to be rated at 8.0 watts. The wattage of any bulb can be calculated by taking the supply voltage (V=12.5) multiplying that by the current draw or amperage (A=0.62) which gives a wattage of W=7.8 watts which is right about on target.
     
    The meter being used in these tests is a Craftsman #82170 30 Range, 10 Function Digital Multimeter. It is accurate to 0.5% when reading DC voltage and 1.5% to 2.0% when reading DC current.

    Comments:
    These 6-Led boards were chosen primarily for their ultra small size and high power light output. After fabricating rear under seat brackets specifically for these lights and making the final wire connections, it became immediately apparent that these lights were too bright for this particular application. The high light output would reflect off my Floor Liners which are made of a rubberized thermo-plastic material, producing glare which would definitely annoy rear seat passengers.
     
    I decided not to use these lights, even for use up front. I tried them out as dome lights and they met my needs perfectly for that application. More details on that can be found at my Interior Led Lighting page.

    Comments:
    These 9-Led boards run at half the light output of the 6-Led boards. At 30mm x 30mm they are still small enough to be inconspicuously mounted under the rear seats without interfering with passengers feet or objects set on the floor. 1.5 watts and 60 lumens each is still considered high power. The hope was that this light choice would give off a less harsh output in this small confined area and have no hot spots. They met this expectation.
     
    They come with a self adhesive backing and are very thin. Thinness is a concern especially for the front passenger footwell as there is a plastic finish panel under the dash in that location and I was worried about having the light itself being hit by passengers legs or packages.

    Fabrication of brackets needed to mount the Led lights.
    While the underside of the passenger side dash area does have a smooth flat location to mount circuit board type Leds without the use of a bracket, the other three footwell areas do not. We would need to fabricate some sort of bracket to mount the Leds to.
     
    The driver side bracket is the easiest to make. If you look under the driver side dashboard, on the steering column shaft, there is a factory welded on tab which is pre-threaded and unused. I am not sure why it is there but is makes for a great place to mount a sturdy bracket made of 1" x 1/4" aluminum flat stock. You can pick up a piece of aluminum 1" wide by 48" long at your local Home Depot, Lowes, or similar hardware type store. Using a hack saw cut a piece off about 4" long. Drill a 1/4" hole in one end. Be sure to file and round off all sides and cut edges including the drilled hole. A 20mm long, 1.0 pitch (fine threaded) M6 bolt will fit into the factory threaded tab on the steering column perfectly. You will need about 5 washers to be used as a spacer between the factory tab and the bracket so the bolt won't bottom out. This spacer also puts the bracket in a better position as well.

    Now for the rear seat brackets. As I mentioned earlier, the 6-Led boards turned out to be too bright for this application, and ultimately were not used. However, this type of bracket may prove to be useful information for someone else’s mod. Below is the method that I used to create each of the two bracket types.
     
    First I will show you how I made the brackets for the 6-Led boards. Starting out with a 48" piece of 3/4" angle aluminum, which again can be purchased at your local Home Depot, Lowes, or similar hardware type store. Use a hack saw to cut off a piece about 3.5" long for each of the two brackets we will need. Drill four 1/4" holes thru each bracket, as shown in the pic below. Be sure to file and round off all sides and cut edges including the drilled holes. If you look underneath the seats you will see two thin metal bars running from back to front. This is where we will mount the brackets using two cable ties per bracket.
     
    If you mounted the led to the 90 degree bracket without further modification the light would shine primarily straight back to the rear of the vehicle. The the material on the backside of the seat hangs down at a slightly lower level than where the light will be mounted and will interfere with the light creating a shadow, therefore I needed to bend the bracket into a 45 degree angle which will project the light downward and backward.
     
    To connect the 6-led board to the bracket I used double sided thermal transfer adhesive tape made for computer chipsets and RAM heatsinks. The tape is very thin and holds quite well. It can be found on Ebay for a very low cost. It comes shipped as 1" wide strips by 6" in length and can be cut to any size you need. This method of mounting the Led board to the aluminum bracket allows the heat to pass thru to the aluminum which can then act as a heat sink for these high power 3.0 watt Leds.

    While I will get into explaining the process of making the final wire connections a little later, I am going to jump ahead here and show you a pic of the light output from the 6-Led boards vs. the lower power 9-Led boards in the rear seating footwell area. The 6-Led boards were simply too bright for my liking to continue with the installation of these boards up front.
     
    I initially chose the 6-Led boards for their combined ultra small size and high power light output. I felt the small sized light was well suited for the small space under the rear seats. Additionally the high power would allow the light to be mounted further frontwards so as to not interfere with the passengers feet while at the same time having enough output to completely light up the footwells.
     
    But, the rubberized thermo-plastic material of my floor liners has just enough reflectiveness to make such a high power led too annoying. Sure the 120 lumens looked great entering and exiting the vehicle. But part of the reason I have the three way switch installed is so that I can turn the footwells on while driving in complete darkness and perhaps leave them on as desired for extended periods of time. What I didn't want was super bright light reflecting up into the front or rear passengers night time constricted pupils.
     
    I was able to repurpose these two 6-Led boards and use them as my dome and cargo lights. They are well suited for that application.

    On to the process of making brackets for the 9-Led boards. These boards are 30mm square which is 1.18". The 1" wide aluminum flat stock used to make the driver side bracket is nearly perfect for these, and no change to that bracket is needed. The 9-Led boards will extend slightly past the edges of the 1" aluminum but that poses no issues at all.
     
    To make the rear seat brackets for the 9-Led boards, use a hack saw to cut off four pieces of the 1" wide flat aluminum stock about 3.5" long, as two pieces are needed to make each bracket. Drill five 1/4" holes thru two of the pieces as shown in the pic below and one in the other two. Be sure to file and round off all sides and cut edges including the drilled holes. Connect the brackets that have five holes to the brackets with one hole, forming a t-shaped bracket. Use an M6 or 1/4" bolt and nut combination to make the connection and cut off the excess bolt length with a hack saw to keep things flush. Put the bracket in a vise and bend the undrilled portion into a 45 degree angle, this will better position the light so it fills the footwell without any shadows. Looking underneath the seats you will see two thin metal bars running from back to front. This is where we will mount the brackets using two cable ties per bracket.
     
    The 9-led boards come with double sided tape pre-installed so after cleaning the bracket with a little alcohol they will attach securely.

    Making the final wiring connections.
    At this point we have run the footwell circuit wiring, installed and wired the switch, fabricated our brackets and mounted them. We are now ready to connect the footwell circuit wiring to the footwell led boards and mount the boards onto their bracketing.
     
    The drivers side front seat footwell is where all our wires started out. In this pic the two wire bundle on the left is the source wiring, again the white wire is the negative from the switch and the red is the positive from the dome light circuit. The wire bundles on the right are the wires that go to the passenger front seat, and to the rear seats. These wires are all 18 gauge.
     

    Wires under the driver side dash panel

    To connect these wires to the 20 gauge Led wires, I will do that in 2 steps.
     
    Step 1, strip all the wires back exposing approximately 3/8" of the copper stranded wire. Twist the three red wires together, and do the same for the white wires. Cut off a piece of red and white 18 gauge wire, each a few inches long. Strip back the ends of these as well. Slide onto each of these cut pieces of wire a 1.25" long piece of 1/4" diameter heat shrink tubing. Insert the three red wires into one end of a 12-10 gauge parallel non-insulated crimp connector, then insert the single red wire in the other end. Crimp the connector. Do the same for the white wires. Slide the heat shrink tubing into place over the crimped connectors, and heat using a lighter.
     
    Step 2, take the other end of each one of the single piece of 18 gauge wires and connect it to the 20 gauge Led wire using a 22-18 gauge parallel non-insulated crimp connector. Be sure to fit a piece of 1/8" diameter heat shrink tubing into place first. Again, make the crimp connection and heat the tubing to make a professional and secure connection.

    At this point we can clean the bracket with a little alcohol, peel the backing off the self adhesive tape pad, and affix the led board to the bracket. Secure the wires up behind the dash trim panel using wire ties and/or tape. Repeat this procedure for the other three led locations.

    Power consumption.
    In the Testing section above, my concern was that since we are adding four high power Led footwell lights to the existing factory dome light circuit we would need to ensure that we don't exceed the factory amperage draw for that circuit.
     
    The 9-Led board amperage was measured 70 milliamps or 0.9 watts each.

    70 milliamps

    After installation, I measured the dome light circuit draw with only the four footwells on. This can be done easily by removing the dome light circuit's 10 amp fuse located in the engine compartment fuse box, and connecting the meters probes there instead. Remember that the vehicle battery voltage varies between 12 to 14 volts, that combined with the fact that the Led bulbs amperage draw will vary with the supply voltage and temperature changes, results in a slightly higher than expected (70ma * 4 = 280ma expectation) 350 milliamp or 4.4 watt total draw from the footwell lights.
     
    If you have read my Led Interior lighting page, you will know that I reduced the dome light circuits power consumption by 25 watts by switching out the factory incandescent lights for Led lights. Therefore, the addition of 4.4 watts for the footwell lighting is well within spec.
     

    Before - Incandescent
    domes, maps, doors, vanities
    3,460 ma or 43.3 watts

    After - Leds
    domes, maps, doors, vanities
    1,420 ma or 17.8 watts

    Led footwells only
    350 ma or 4.4 watts

    Led domes, maps, doors, vanities, footwells
    1,650 ma or 20.6 watts
