The ground distribution diagram I got from Alldata, but it IS a factory diagram. No prize for you, Dan...the prize box is empty...sorry.
I could not upload the complete diagram...it's too large for here, but if you need the complete diagram, I could e-mail it to you. This is strictly the instrument/dash diagram, not the entire car.
I had posted here before the concept the GM uses for numbering their connections. I'll see if I can locate that, but it has to do with odd/even numbered connections being on the left/right side of the car, and it goes on to tell what part of the car(engine compartment-dash-passenger compartment-rear). Once you learn the system, finding connections is a lot easier. Then again....it's even easier to look it up on the diagrams if you have them!
It has always bothered me that most manufacturers did NOT specify where this/that connector/ground/splice was located in a harness, until the mid/late '80s....sure makes it a lot harder on us old folks to find the stuff....
