I'm having wireing problems with my 89 fifth ave. Here's the run down turn on headlights and hit the brakes lights on dash and heads dim a little and a smell of melting wireing come from somewhere. Found the pink wire next to the green wire for head lights on head light switch gets really hot untill you let off the brake then cools down. Things I've done so far to track this down cleaned all grounds on tail light wiring, cleaned all the tail light sockets also front, cleaned all grounds on front fenders, fixed wires that where chopped and tied togeather with black tape.Now sodiered and shrink tubed and also taped near driverside kick panel also cleaned grounds in that area. Things I think that maybe left to check bulk head connector ,Brake light switch , turn singnal switch. Any help would be great

Well guess it's going to be fun to fix LOL most of the pink wires I see run to the head light switch and to the brake light switch then to the turn collumn

I'm a memeber there for about 3 years now and not much help. they ran off all the good guys that knew anything about cars. It was a great site a few years ago.

Belive it or not it's not really that far off the wiring harnesses are pretty close to what I got I see where the pink wire that gets hot on the head light switch goes right down to the brake light switch .So theres a chance that the switch is bad . The guy that had the car before my put a junk yard switch in so who knows.Thanks for your help

If that's the cause the quickest two checks you could make is to disconnect the harness to the rear--normally in the left kick panel and see if that clears things up. If not, then disconnect the turn signal connector

At least that will isolate the trouble some
