I am swapping the Olds 307 for a sbc in my '86 Cutlass. I plan on keeping the a/c, lock up trans and cruise. I know those items are all controlled by the ecm. I do not plan on using the egr, electric q-jet, etc. Do I just use the wires for the cruise, a/c and trans and cut the rest? I guess the engine light will always be on, but I can disable that. Anyone ever do something similiar?
TIA
