Hi, I'm building a 56 dodge/fargo pickup and I need some help with figuring out the wires on the wiper motor. I believe the fella is original just by the way its mounted in the truck. Coming out of the wiper motor is a black, red and a light blue, theirs also a peice of wire hanging off the wper motor obviously a ground. On the motor itself theirs "auto-lite epf 4101 12v. Any help is appreciated and thank you
