Good luck. This should be helpful for a lot of people.
The harness I am using came from a 87 truck (thanks beater c-10), I also had a 90 suburban I bought for parts and I have that harness also to save for anouther project. Anyway I will show everybody tomarow where the stock suburban harness came out of the truck. It is in the same location on this 86 truck because it had the esc distribitor from the factory. I am going to use this hole.( It's on the pass side also)

I looked at a 92 today and they would probably have a little extra wire if you use that harness but not so much that you could not make it look factory if you wanted to.
