Ok, so here is a picture (1st pic), that I have of a spare motor and washer pump. I circled the 3 pigtail connections. Is yours like this? This comes from a car with Pulse wipers and yes has wires that you can see Red and Black, but I believe they all do have that. Now, here is something that I experienced a long time ago. ACDelco was offering a different looking, but functional, wiper/washer assy, but you had to splice in or use an electrical adapter to your current wire system to make it work. It looked like the 2nd picture on here. That one had NO wires inbetween, but appears to be only 2 pigtails.
