I have bought a new wiper motor for my 1970 Cutlass Supreme. Part # PG-WPM156 Its supposed to be for concealed wipers and on demand pump. It has 2 wires coming out of it that I don't remember from the original. Does anyone know where they are supposed to hook to? Trying to figure out how to hook this back up.

 

This is a 71 wiring diagram and the wiper hookup should be the same.

I have the book for my 70. The problem is the replacement motor has 2 extra wires that weren't on the original. From what I can tell they are for a surge option if you have it? Not sure but I will see if everything works without them . Thanks for the help.

 

I used WPM142 and it didn’t have the extra wires. Did you replace the pump too? What part number was it if you did?

I used an ACI 172212. It looked the most like what was originally on there. I got it on Rock Auto and it was listed for the 1970 Cutlass but not the Supreme, weird. But seems like you see that in a lot of applications.
