    Cottontop 11's swap. So it begins

    Got to taking the tbi stuff out of my old harness last night. Gm should be ashamed of themselves for that gorilla glue like substance they submerged the passenger side firewall passthrough with.

    I agree 100% about the passthrough. I am ashamed of them. Hurry up so you can load some pics!

    a heat gun helps soften it so you can pull the wires loose.

    After one or two wires I knew something had to give. I went and got the ole heat gun.

    I had same problem on my 96 harness. Its a simple fix the harness in held in by a clip behind glove box. Just pop glove box out and youll have access to it. no cutting or heat gun needed.
