Ok LT1 5.7 engine has 2 body harness conectors.
A Firebird 3.4 Has Has 1 Conector to body and Engine.
I took the 5.7 engine Harness Plugged Everything In But the Car would not start. So I recently found out , that it was not firing on 2 injectors becuase it was a 6 cylinder. So I went to All Data , I traced the wire diagram from the connectors , I found my main Power wire for the other 2 injectors. And I ran it into 1 connector. The car started started ran evenly but now when it gets up tempeature the cylinders load up. There were no cutting or splicing , I popped 2 wires out that was for a serial wire and the other injecor and pinned it into the other connector.
