Wiper motor types and such

[cookieman77]

So I’m in the process of rewiring my k5 when I discovered I was missing a connector for my wiper motor. Went online to try and find a replacement online and no luck.
Found a parts truck to take one from and found a different motor style so I just need clarification.
Mine has 2 connector spots and parts truck has 3 alongside some lines that go to it

According to the vin, mine is a 78; although it has a few things that definitely were added. Parts truck is an 83 k10.

Not old enough to have much gm knowledge yet so what’s the 3rd connector spot?

the bottom ww motor has a mechanical washer pump, it would need wiring for off on. Your 78 should look like the bottom, but it could have had a more modern square ww motor swapped with an electric pump at the washer bottle. The mechanical pumps failed regularly, could be rebuilt a couple times.

Appreciate the info.
Figure I’d get the connector I’m missing then and keep my pump while it’s alive.

Do you happen to have a diagram or knowledge for what the wires should be at the connectors or know where to find one?

Haven’t had any luck yet personally but I might be searching wrong.

I should have wiring you need off the last 78 that I parted if you do not find it locally.

Yeah it’s just the one connector and stuff I’m missing.
Found a part out locally but haven’t had time to make the trip and haven’t gotten a response recently.
