'90-92 TPI Wiring Harness
Hello everyone, I'm looking for a good or decent 1990-1992 TPI wiring harness. This is the newer speed density 1227730 harness that was last introduced before the new LT1 came out in 1993. The harness doesn't have to be perfect and could have damage, but as long as it is repairable in terms of harness connectors and pigtails and of course the wiring loom. If it is possible, I would like the positive and negative battery cables with it too. Thank you everyone.

Hi, thanks for your inquiry. If you can, could you post up some pictures for this harness and ECM you have? You could PM them to me if you would like. Thanks again.

Hello, do you have any pictures of this harness you have? If it was an RS with TPI, it has to be from a B4C interceptor. All other RS Camaros were TBI. If you could get some pictures of this harness that would be great!
