wiper motor hook up
 

getting down to the end on my wiring. I need some wiring help on my wiper motor and pump. I searched the forum and found where the system basically works off one power source to motor and all the switch wires are some sort of grounds. Painless only gives me one wire I assume it is a power wire. I have all three pigtails one on the switch and one on wiper motor and one on the pump. I know the gray and black wire on switch is for the light. So I got 2 wires on Motor 4 on pump (Two pigtails) and 4 remaining on the switch after I hook up the 2 for the light. Anyone have a simple simple drawing on this system. The oem stuff pretty confusing to me at first glance. Thanks

Attachment 2032915]still need help. My motor and washer pump has three pig tails. One with three wires one with two and another with two. I have search all 121 forum threads on this and all seem to be for 67-72 motors which are different. I have also got no luck on u tube, LOL I should have bought a 67-72 all kind of help. My dash switch has 7 wires I know the gray one is power for the dash light and one has to be a ground I presume. My research says the constant power should go to the middle yellow and black wire in the middle of the motor pigtail . then the yellow and black wire on the pump jumps down to the power also. then I get into trouble. not sure what the third pigtail does . I assumed the solid black wire on the switch was ground but it is not. So confusion has set in any help would be apricated. I attached some pictures for help.

Well I first replied, thought it was 67-72, I'll look and see if I have any books that might help on the Square body, I havent done much with wiring on these,

does someone have a wiper motor with pigtail wires that match my switch color wires that would be a great help. I my have the wrong year pigtails off another year square body.

I will refer you to this thread. I was going to suggest you pm member Hatzie when I found this thread. If it doesn't help you, you still have that option.
