    I am trying to find out if the wiring harness inside the cab under the dash is the same in the diesel blazer and the gas blazer. I need to put a gas engine wiring harness on my 350 motor, but I am not sure if it will work with the diesel wiring harness under the dash.

    Any advice?

    Thanks in advance.

    Sorry, but the harness was destroyed by the mechanic I had do the swap out.
    Needless to say I have someone else finishing the job.

    You don't happen to know where I can find a complete wiring diagram for inside the cab and in the engine for the wiring harness for a gas engine and a diesel engine.
