Specv1973 Posted September 12, 2010 Share Posted September 12, 2010 Hey gurus......I need help with my fogs. I just ordered all new PIAA bulbs for the headlights and fogs as well as new wiring kits with relays etc based on the pinned forum on getting brighter lighting in here. I just ran through the wiring a little bit on my fogs and they already have a relay setup. It's all Bosch lighting,relay,etc. Was that a factory thing? Anyway, I've got a problem. There is a green wire (ground?) and a white wire (hot?) leaving the relay going into the cab and to the factory switch in the console (maybe this is a factory setup, hmmm) and coming into the switch is the green, the white, and a new purple wire. Is that purple wire hot or ground or switched or not, I dunno. Looks like it comes from the steering column area I'm guessing. Tried to follow the wire loom to see where the purple wire comes in to the mix, but I can't see it for sure without taking more stuff apart. Maybe it's tied in to the headlight switch so the fogs can't come on without the headlights first? I'm lost guys, and the switch dosen't tell me where the wires go to either on the pins, and I already hooked it up wrong once and blew the fuse to my passenger headlight. wtf? I've looked at every wiring schemtic I could in the FSM and the Chilton, but no of them show the fogs, only the headlights.......ahhhhhh! Link to comment Share on other sites More sharing options...
Specv1973 Posted September 12, 2010 Author Share Posted September 12, 2010 It's amazing how things come to you after you read your own writing....I fixed it with my test light like I should have before I confused myself. I'm a dumbass. White is hot and green is ground for the fogs. The purple wire IS tied into the headlight switch. Fogs won't come on without headlight switch on. So white and purple go on the 12V side of switch and green goes on the other side. Duh! Makes sense now....whew! Link to comment Share on other sites More sharing options...
silverton Posted September 12, 2010 Share Posted September 12, 2010 I was wondering what that purple wire on my column was for. Now I know that all it needs is a 12v source for the fogs to act independent of the headlights. Link to comment Share on other sites More sharing options...
Specv1973 Posted September 13, 2010 Author Share Posted September 13, 2010 (edited) It also cuts the fogs off when the high beams are on. Not sure how it does that though. Edited September 13, 2010 by Specv1973 Link to comment Share on other sites More sharing options...
