Does any one know how many connection points there should be on a wiper motor for a 1972 Vette. I had the motor replaced last year and the new replacement only has 3 connection blades . The old one has 4 three inline and one above the three.Since the replacement is in place the the wiper door does not function.

Any help or info greatly appreciated Runamuck

The factory wiring diagram for 72 does show 4 wires. The three grouped include a 18 gauge yellow hot lead, 18 gauge light green and 18 gauge light blue both going inside the car to the wiper switch. These can tie into to the delay relay if the car has delay wipers.

The fourth one does tie in with the wiper door control and override switch.

If you like send me your address and I will send you a copy of the 72 factory wiring diagram.
