I just bought a 1979 F-150 4wd with a 351M motor. My problem is a the lights, headlights work fine. The front driver and rear passenger turn signal work. front passenger and rear driver side doesn't. the rear passenger side brake lights works but not rear driver side. i have no taillights at all. i was just wondering if this is a just a wiring problem or something is shorted out. i have no clue. would it be easier to just get a new wiring kit? any help is appreciated. Dan

 

There are a few other threads regarding this problem.

It is either with the stoplight switch or the signal switch,

Or a grounding problem.(this one I doubt though)

I changed all sockets on mine (park lights in rear, park lights in front, still need to change sockets on back - up lights) but I'm gettin' closer i think i do have park lights in front and back now. still gettin' bugs out in mine, good luck.
