So when you swap out the tbi engine, what do you do with the old harness and ecm? new ecm is stand alone and will only start and run the engine.

Pull as much of the harness and computer as possible and then call it good?

I have been scouring lt1swap.com for info on the ls wiring, but havent found a good resource for 87 wiring and what is removable and what needs to stay.

Really appreciate all the info on here. Making the swap very feasible.
