    LS1 Swap into 1992 Chevy Pickup

    I'm currently helping with the wiring for a LS1 Swap into a 1992 Chevy Pickup. There are multiple ways to wire the LS1 into a 1992 Chevy Pickup. I decided to de-loom the bulk head connector and re-purpose the service wiring (Bat + / Bat - / MIL / Fuel Pump / Ignition On-Start / ALDL) from the old TBI computer to use on the LS1 computer. The TBI system wiring was un-pinned from the TBI computer. The original bulk head mounting plate will be re-installed and resealed. The end goal of the wiring is look factory.
