The factory fog lights are wired to illuminate via the fog light switch located on the headlamp/turn signal stalk
(combination switch), only if the low beam headlights are switched on. The fog lights also shut off when the
high beams are switched on.
My preference is to have the ability to switch the fog lights on when the parking lamps are on, as well as to
have them stay on while the high beams are activated.
To accomplish this, we need to do two seperate modifications.
Part One:
Fog Mod part one is done so that the fog lights will turn on if desired using the factory switch anytime
the ignition is on and the high beams are off.
Remove the fog light relay located in the engine room relay box and bend the top left prong #2 so that
it no longer inserts into its usual location. That was where it was getting power from the headlamp circuit.
Take a short piece of 14 gague wire and crimp on a fully insulated female quick disconnecting terminal
with a 0.187" tab. Do not use a standard 0.250" tab disconnect because it will not fit tightly enough.
Connect the disconnect to the top prong of the fog light relay (the one you just bent).
Run the other end of the wire to the bottom left prong #1 of the IG relay. My vehicle did not have an IG relay
installed so I was able to use a 0.250" insulated male quick disconnect 'crimp type' solderless terminal which
plugged directly into prong #1.
By choosing to obtain 12v positive power from the IG relay, the fogs will activate anytime the vehicle is on,
and shut off when turning the vehicle off, if left on.
They will work even if only the DRL's are on.
Part Two:
Fog Mod part two is done so that the fog lights will remain on (if the factory switch is on) while the high beams are activated.
Remove the three philips screws securing the steering column lower trim cover. Only one screw is visible while
the steering wheel is straight. Turn the wheel to reveal the other two. Pull the panel down and to the
right to remove. Unplug the C12 combination switch harness and connect wires going to pin 16 and 17 together.
I used a blue t-tap splice connector. The white with black stripe wire going to pin #16 is the ground wire.
The red with green stripe wire going to pin #17 is where ground is needed so that when the fogs are switched on
ground is passed to pin #11 then to pin #10 and on to the front fog lamp relay.
This will allow the fog lights to remain lit while the high beams are on.
