    Which wires can I hack off? I know there\'s a bunch--TBI-carb swap

    Okay, I'm no electrical guru, I could look at a wiring diagram for hours with no avail. Tomorrow one of the tasks on hand will be to sort through the miles or wiring under the hood. I will trace all wires before I cut them, are there any that you know of, that I will absolutely have no use for and can just cut? I want to keep everything as simple and clean as possible, and that is just impossible with sensors here and relays here and relays for those relays across the manifold and blah blah blah. Anyway a little advice on which ones I can cut, which ones I absolutely can't cut, would be appreciated indeed. Where ya'at Pureinsanity, I need your help again bud 8)

    What did you do with the TBI?
    THe TBI on the Second Gen trucks istall not much different than a Holly Projection. On the fire wall will be a big gromit they all pass through to the ECU behind the glove box. Unplug the ECU and pull it back through the fire wall. Everything should unplug. Don't cut that Harness. You can sell it. If you have the whole EFI system I would be interested in buying it. There are several sensors on the engine that you won't need.

    You're throwing away money by doing so. Pull them all to one side, and tape them up, or trade/sell the existing TBI wiring. It all unplugs for a reason.
