Harness help 1991

I am in the process of final assembly of my 1991 cummins suburban , I wanted to repair/ simplify my harness.
Does anyone have a "map" to the pins that are in a 88-91 suburban firewall conector?
Not worried about body conections just the engine harness.

Any help would be appreciated.
