May 18, 2009Hi Guys,
I am having brake light troubles. Out back on the passenger side my tail light is acting funny. When I turn my lights on, the passenger side is very dim. It is also dim when I turn my right signal on. When I hit the brakes (with the lights off) it comes on also very dim. When I hit the brakes with the headlights on, the light doesn''t come on at all. I took at look at the bulb socket and it seems ok, but only the ''headlight" filament would come on at all, the brighter brake light filament doesn''t come on at ever. I a trailer light connection wired on last year and my tail lights have been acting funny ever since.
So, to finally cut to the chase, does anybody have a color coded wiring diagram of the tail lights for a 1978 (F350, if this matters). I''d really like to get my lights working properly.
