Yeah I have the same question. Does this gray wire connect to the foglight switch? Does anyone have a clear picture? Maybe with idiot proof arrows or something. On my last car all i had to do was clip a wire and splice it to another. Same I'm guessing but this is a confusing post. I don't want to snip the wrong wire.

when you pull the fog light relay out and look at the wires going into the plug, the gray wire feeding the relay is what you want. Snip that as it is the wire that toggles the relay over to turn on the fogs when the low beams are on. Then take the relay socket end of that wire and connect it to the brown wire shown above in the pictures to supply power to toggle the relay when the parking lights are on.

Hey Guys,

I know this thread is old but Im planning on doing this mod when I get home from work. I looked a my car and found the harness (not the brown wire itself) that I tap the grey wire into.

My problem is - where the heck is this grey wire?!

Can anyone point it out specifically on this picture (arrows or something)? That would be great!

I just did this mod.

Took about 20 minutes and lots of swearing. BUT it works and IM SO HAPPY.

Thanks guys!

I plan on installing HID's in my fogs. Should i worry about anything w/ this parkinglight/fog mod? could it handle the extra amps? or should i just get an entirely different switch?

Papispico

how do u pull that little box out. i tried but seemed to only pull out the cap part with the 3 or 4 pronged ends...i cant pull that entire thing out for some reason...

when i lock my car, my parkinglights and side mirrors flashes, if i do this mod... will my foglights flash too???

Papispico

if u keep the button pressed....then yes.

errgelistic

eww.. nvm. any way to mod it without that happening?

Papispico

yea....dont leave the button pressed active

I have my fogs wired to turn on without headlights following the steps in this thread and my fogs don't flash when locking/unlocking even with the button "on".

Papispico

your using ur scion alarm. Since im aftermarket my fogs blink when my parking lights blink...as long as my button is activated.

I just did this, and it's definitely a great, quick mod. Gives the car a real bad ___ look with just the fogs on. The only difficult part is trying to clip those wires; there's not a lot of play in the harness, and there's not a lot of room to get your hands in there!

Dur here we go, pics are kinda dark but illustrative:

i'm bringing this back from the dead.
I just tried it and now on the first click i get no light at all... no parking or anythng ,... on the second click everything is fine..
and when i hit my alarm everything including low beams blink..

what did i do wrong?

Papispico

hm that sounds odd. i dont know if u connected an extra power wire from somewhere. or what.

When u say click...do u mean pushing in the OEM fog button?

sorry to bump this up but has anyone done this with VRD fog lights? I seem to have trouble making it work with VRD foglights
