Just started my 72 camaro with tpi motor and 700r4 trans.If anyone has this in mind i recomend the painless wire harness,i thought i was going to use the harness from the doner iroc,well that will get you mad in a hurry,the painless was 420.00 bucks but i think it was well worth the $.I turn on the switch,fuel pump primes,then it fires right up like it came in the car.
