I have two cars an 86 parts car that originaly had a 2.8 mpfi and an 86 iroc. I'm swaping a 95 lt1 and t56 into the Iroc. Are the plugs on the driver side firewall the same. If they are I can get most of the harness spliced together before I even pull the motor out of the Iroc. I believe the only wires coming out of the firewall are for the lights, guages, ac and injectors which both cars have. I'm not sure if the pinouts are the same. Does anyone know if this will work?
