anyone have a diagram or picture of which color cable connects to reach prong on the back of the switch 1964 dodge dart windsheld wiper switch its a two speed motor thanks in advance
The FSM wiring schematic details all colors and wire gages. Indeed, I just saw a schematic for your year in another post (early A forum). I have at least three 64 & 65 wiper switches and none have that white plastic box on the rear. Perhaps that is for a "washer" function. The black square bulge on the rear looks like what is on variable-speed switches, but Google Images is smarter than me.
64 and 65 FSM are probably similar in some areas and definitely not as far as the wiper switch. That electrical box hanging off the side looks similar to the convertible top/rear window circuit breaker found behind the driver's kick panel on a 65/66 A Body. As far as the rest of the contacts, they are not even close to a 65 single or variable speed switch. You would be ahead of the game if you can find a 64 manual or maybe if someone has the manual they could scan the appropriate pages for you.
EDIT: are you sure it's not a variable 2 speed switch?
