I have a '72 and I bought an aftermarket rotary wiper switch to put in a custom dash I made(http://camnick.home.att.net/dash.htm).I was just told that 68-72 Chevelle wiper motors are wired hot and get their ground from the switch. Is there anyone out there that produces a switch (preferably rotary), or is there one from a different vehicle I can use. I don't have that much room in back of the dash, so size of the switch is a concern. Any help would be appreciated

Just one thought. Older GM cars used a rotary switch. The body was grounded to provide the ground to the individual wires. Maybe something like that. You will need the mating connector and the large eyelet lug to ground the switch.

I have a rotary style switch for 64-65-66 . It is a grounding type switch. It has three terminals. It grounds one for the washer. Of the other two, both are grounded for low and one is grounded for high. Nothing grounded for off. These years use a seperate harness for the wiper motor. if you can score a switsc, motor, and harness off the same car, the motor should bolt on. just run an ignition hot to the wiper harness, and your good to go! GOOD LUCK, STAN
