I already searched and all of the diagrams I am finding are wrong. I have found 3 different instrument cluster diagrams that show the pin location, wire color, and description for an 87-93 cluster....but those are wrong. The pinouts were changed with the addition of the airbag, and all the diagrams actually show the 91-93 cluster. I am trying to find, what I think is, a bad ground somewhere in the harness...or possibly a crossed wire. Thank you.
