Wanted to see if any one knows what is the quickest way to access the wires to the Fog lights.

I want to run a power wire to it so when my headlights are on the fog lights also come on.

To turn on fog lights as of now you have to turn it to the on postion and pull out the ***. I tend to forget to put it back to off or auto when i park the car and it drains the battery.

I tried looking for the HOT fuse for it and running power to it but could not get i it work.

Looks like i will need to add a relay and a run the power directly to it.

I think thats a bad idea... yeah you could add a relay but chances are good the car might throw a code.. Can you say VOIDED electrical warranty?

If you are dead set on doing it, the wires can be accessed underneath the front bumper, just bypass them, add a relay and tie them into the switch..

I wouldnt do it...

Are the fog lights on the same electrical circuit as the other lights? If not, I am sure you can wire them at the fuse box.

If they are, then lorinserbenz is correct I believe. I too think it is a bad idea.

I could not tell if it is on the same circuit. To avoid the warranty issue i was planning to just disconnect it entirely form the system and do my on switch.

But since you guys brough up the warrenty issue it is making me think. But I really kinda like to have those fogs on. It looks aggressive.

It's a holdover from the switch/wiring design they've had for years (even my 1970 SL works this way). They've never done a separate foglamp switch as is on most other cars, so when they went to the auto feature...the switch wasn't in a pull-outable position. Now, that might have been rethought, but Noooooo.
