I just got an intake, dist., tbi, & 'puter. The harness was canableized. Will a harness from a 350 inter change? Or do i need 1 for a 454? I thought about calling Painless wiring, any ideas? This is off an '87 3/4t Suburban. Thanks ED Get use to the view. Because, if your not the LEAD DOG the view never changes.
