Will a wiring harness from a 1978 el camino fit my 1980? The wiring harness is for a 350 and mine original engine was swapped for a 350. I don't need it to be an exact replacement, I can add in things or change things, but would it be pretty close?
 
It'll be a pretty much a direct fit. The only differences are the '78 harness didn't have a electric choke but the '80 one will. So the '80 will plus it'll have a three wire/two blade oil pressure switch plug for warning light trucks & that plug with the single tan wire for gauge trucks. Then the A/C harnes plug may be different.

Great, thank you
