Do you need the body wiring diagram, the Federal engine control wiring diagram, or the California engine control wiring diagram for a 1985 S-15 Jimmy 4X4?? What size engine does your GMC have? I would be happy to scan my Chilton's diagrams and email them to you. Reply to coulomb4000.com and I will scan what you need and send it via email.. Put "GMC wiring diagram" in the subject line, so I know what is about.. I am working on my 1986 GMC S-15 Jimmy 4X4 and have 2 manuals to work from. That is how I found this question.. Dave
