ECM wiring
Posted: Fri Dec 23, 2016 4:56 am
I've got a 74 Baja 2.2 ecotec.it came out of a 2002 Pontiac Grand am.got the whole wiring harness,bcm,ECM,fuse boxes,etc.the harness for my bug was shot so I'm putting the whole thing in my bug.my question is if I take out what I don't need will it work without having to have the ECM reprogrammed?
