this is my first engine swap and so far so good. i drive an 89 firebird formula TBI with 227,000 and counting. i purchased a toataled 86 iroc 305 TPI with 74,000 miles on it. im swaping the motor, trans and rear (cause its posi) the drivetrain is out the the cam and im wating for the weather to break to start on my bird. pople have told me im going to run in to problems trying to put that harness and ecm in the bird cause of certain connection and the flip up head lights. its this true. what i need to know is can i use the ecm and harness from the cam with little or no problems. or do i just need the engine part of the harness and what dose that constist of. and info would be a huge help cause when it comes to wiring im lost.

^ my thread on wiring harnesses. The S&P people also have a TBI-TPI conversion kit IIRC. Just go to their online catalog on their site, same page as I said my kit is on.

 

This might help you out some...it did me....
