Wiper motor wiring

Postby roelke » 17 Dec 2007 19:58

Please Help!
I have a 1970 challenger with a variable speed wiper motor and a two speed switch. I am installing a 1974 ralleye dash which has a varable speed switch. Problem is the wiring harness has 6 wires and 1974 switch has 8 connectors. I need to know how to make this work if its possible.
The switch part # is 2770380 and the motor # is 3431077.

I do not think it is possible, but maybe someone else knows better?

Even if you could get the connector to mate together, the circuit would be 'seen' as an open. I dont think this can work. Why not switch the switches themselves?

I went through this on my GTX...... A three-speed wiper motor switch will make the two-speed motor run wrong and the two-speed switch will make the three-speed motor run even worse. If you are going to an R/T setup, get the three-speed motor and the drive arm that mounts to it (the one from the two-speed motor will not mate to the three-speed's output shaft) and do the job right. If you ever go to one of the big air cleaner setups, the wiper motor change will already be done when you do it.
