90-92 tpi wiring harness question
Will the wiring harness from a 91 corvette c4 tpi fit my 92 rs ecm? Or will i need the corvette ecm as well? Or better question is this even possible?
Re: 90-92 tpi wiring harness question
If you have a 91 vette harness just get a 7727 ecm and prom. They were mounted under the hood.
If you need one I think I still have my 90 ecm (same as a 91) has chip and all.

will it plug right in with all the camaro connectors or will there have to be some adjustments ?
Re: 90-92 tpi wiring harness question
No the corvette used like 4 square electrical connectors the f-body used three rectangular ones I believe. You can use a vette harness though and just under hood mount the ecm.

Is there a thread somewhere explains what I'll need and the diagram? That would make things a whole lot easier...
