1983 Ram 4x4 PU Wiring Question and advice needed.

[wytmagic]

My 1983 Ram has wiring problesms. The rear tailights and brake lights will not work.
I have a bad ground I think. But I need to know the proper wiring for the brake light switch. The wiring was off, and I need to know which wire color pair goes toward the driver and which goes on the engines side.
Does anyone have an 83?
Left turm signal works, right does not, and flasher only works when turn signal arm is activated to turn left. It is really a confusing problem.

Also, Someone put a sportscar steering wheel kit on the truck which I hate. Does anyone have a factory steering wheel lurking in their shop? I would like to replcae the sporty small one. It is almost impossible to see the speedometer!

Any help would be appreciated!\Wyt
