3 wire wiper motor? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm just about done my Painless harness, really close. One thing it does not cover, however, is the wiper motor as it is supposed to be plug and play. Well, it isn't.... I have 4 wires that go to the motor pre-wired to 2 plugs, and one that goes to the washer pump. My wiper motor only has three terminals on it, so that is where the problem is. It used to work right with the old harness, and even had 2 speeds. The pump never worked though. Any help would be great. Thanks!

See if you can access this website, it is closed sometimes but I just checked it and I got in. It gives a ton of info on the wipers.
