Hey guys, I just picked up a 72 Cuda. Nice car, but the wipers are not working. I pulled the switch and I have voltage at the switch. I pulled the wiper motor plug from the firewall and tested there, I have voltage there. Could be a bad ground or a bad motor. I want to run a jumper wire direct to the wiper motor (3 speed). Which wire should I run the jumper to (or does it matter) and which wire on the motor is the ground?

Laine.
