305 to 350 engine wiring harness ?
Hi guys,
i think the majority of my cars little problems are all to do with dodgy engine wiring harness, lots of cut wires etc, i recently replaced my MAF burnoff connector and the relay and when i plugged it in the car wouldnt start unless i held my foot on the accelerator, and even after it had warmed up it ran like crap ! bizarre.
Anyway, a friend of mine has an 87 5.7 GTA but he is removing the TPI setup for a Carb instead.
mines an 87 5.0 GTA, so i was wondering if his engine harness is the same as mine ? his is in really good condition so i was hoping to just swap it over for mine and hope it cures some of my electrical problems

cool thanks man.
One thing though, his has a digital dash and mine has a stock one, he said the connectors look different at the firewall ?
