Wiper Motor Help
I have bought a new wiper motor to replace the missing one on my corvette. I'm not sure the where the correct wire conection go, looks like a 3 prong on the wiper motor and two on the washer unit, plus one wire set coming from the motor. Any help would be appreaciated. (1971 LS5 4 Speed)

The 3 terminal connector goes to the motor. There are two wires that have the bananna type connector ends (if they are still attached) these are for the washer. There is one large Red wire coming out of the motor. This wire needs to be connected to the wiper door switch on the passenger side near the wiper door actuator. This keeps power from the motor until the wiper door opens fully. There is one more wire you did not mention and this is the most important one. One of the bolts that hold the washer pump on should have a spade connector (male) under the bolt head. This is to ground the whole motor assembly and should run down and ground at the blower motor ground but can use any ground you find. If you do not ground the motor assembly then it will not work. This assumes that your wiring harness and wiper door system are stock.
