Hey everyone, new member here, recently purchased an 1988 IROC Z.

Anyways I searched around and found a lot of help as far as wiring diagrams go, but my issue is on my front wiper motor, the pigtail for the 3 pin connector does not plug into my wiper motor. I recently picked up a new wiper motor but the connector does not plug in. I am wondering if i am missing a certain harness, or if someone has changed the connector on me. I have some photos here of both connections, if someone is able to shed some light, or perhaps show me a photo of how theirs is set up, it would be greatly appreciated.

I went to the local GM dealer and they could not help me, except for providing a possible part number of PT109 which, after googling, looks nothing like what I need lol

 

I believe the 1st three photos are of a weather-pack connector like this one from Prowire (#12020829).



This will plug into a MALE weather-pack connector (#12020827) on a factory supplied pigtail, like this;











The other end of the pig-tail that plugs into the motor is a 3 way Metri-Pack 280 sealed Female connector #12059612 I believe. 280 means the blade size is 2.8mm.







Hope this helps.

 

Here is what the terminals look like. I searched for Delphi connectors and Weatherpack connectors to find the pictures.

Dephi has some documentation.

 

This is a huge help, thanks for this!

 

Your welcome. Hey, part#12059612 for the Metri-Pack 280 may have been changed to #12040977. At least WAYTEK has it this way.

 

That purple yellow and black pigtail, what harness do those wires go to?
