    87 Z28 / 97 T/A LT1 swap close to completion

    I have the LT1 in car, car was originally TPI. motor mounts hooked up, fuel lines done, P.S lines done, etc, etc. All wires are hooked up except C100, C105, C210, C220 and C230 connectors. On to wiring. I have tried looking at schematics, lt1 swap start to finish thread here, lt1swap, wiring for dummies thread here, etc and I dont grasp some things well but I think I am very close. IF I understand correctly this is how i will wire my 97 LT1 from a T/A: PLEASE correct me if I am wrong.

    LT1 C100 PIN A PINK pwr feed from injector #9 run to C207 PIN G wire at my 87. This will feed pwr to 4 of my injectors

    LT1 C100 PIN G PINK pwr feed from IGN (this is something to do with ignition, not sure what) run to any factory switched pwr wire PINK on my 87?

    LT1 C105 PIN B PINK pwr feed from Injector #10 run to C207 PIN B wire at my 87. This will feed pwr to my other 4 injectors

    LT1 C210 PIN C ORNG pwr feed from PCM run from this to C100 A4 wire at my 87. This will feed pwr to PCM

    LT1 C210 PIN A PRPL thft deter relay to starter I believe I will run a wire from this to C100 B4 wire on my 87

    LT1 C210 PIN D RED fuel pump feed run from this wire to C207 PIN D wire on my 87. This will pwr my fuel pump

    C220 PIN E PINK pwr feed from PCM IGN run from this wire to a factory switched pwr wire on my 87?

    C230 PIN G PINK pwr wire for an engine sensor? (not sure what this is for or where to run it)

    I understand I would still need to wire ALDL and ALT. For now I am just hoping to make the car run and then move forward as I go. Hopefully someone is kind enough to help out. I don't want to hook up the wrong wires and fry the PCM or worse. Thank you.
