New to the Fiero world. Just got a 87 GT 5 speed, I’m curious what all is involved in putting a 3800 in. I assume the engine, harness, ECM. Is it hard to make the dash jive with the new mill. Do motor mounts line up is there a commercial kit or pretty easy to fab up what you need. Any info would be welcome. I at no time said or even suggested in any way that this is the only way to do a swap harness. I did state that this is how I do a swap harness and with many years of experience in wiring aircraft for both the Canadian Air Force and civilian aviation as a liscenced avionics tech I like to think I know atleast a little about wiring.
