I have a 1982 3/4 chevy 4x4. Installed a 1993 tbi 454(whipple supercharged) with a turbo 400 manual valve body. I unhooked all unnecessary wires. I have the 16147060 ecm with the whipple prom. It runs but has serious detonation issues. not sure if my wiring is correct. Does any have the correct schematic for this 454 ecm?
