    Hey fellas


    Im in the final stages of my 5.3 swap into my 97 chev suburban.
    I ordered a psi conversions stand alone wiring harness
    Where is a good resource to figure out the 1997 chevy sub factory wiring harness?
    I need to figure out the two firewall connectors
    My Haynes manual is useless, not enough detail


    Any help would be appreciated.
