Thanks.

Another option would be upgrading to the square 4 position WeatherPak that was used from 85 on. I've used them on 3 trucks with no issues. I don't remember the GMC pinout but it's in the wiring manuals.

Mouser electronics sells the all the individual pieces for under $7 total.
The last time I ordered these pieces I saved the parts needed as a Mouser quick access project.
