Here's the color code right out of the book, with the terminals looking at the back of the switch, "A" terminal at 12 o'clock = Red (low) , 3 o'clock (kinda from the center actually) "P" = Black (park) , 5 o'clock "B" Yellow from ignition (Battery) , 8 o'clock "F" Green (High)

wiper motor grounds to cab/body via mountings. For giggles, make sure you have a GOOD ground, and remember, this is POSITIVE ground 6v. the guts of your switch may be all grubbied up too. they're not too hard to clean iffin you go slow, keep track of what goes where, and dont let anything sproing away from you.

The book also makes a point of Cautioning : Do NOT attempt to manually rotate the wiper blade shafts of the electrically operated wiper. To do so may make the unit inoperative.

Thanks, So i now my truck is all wired up gauges, lights charging and starting systems. Everything working great 12 volts. Whats left blower motor and wipers. Since they are positive ground,Would I hook the negative to where it says Batt? Won't this cause a conflict since it will be the opposite of the rest of the wiring?

 

The blower motor and wipers won't care about polarity. They should run the correct direction regardless of whether they are on a positive or negative ground.
