Thread: 4L80E to Auto Meter electronic speedo, Dominator EFI.

    Default 4L80E to Auto Meter electronic speedo, Dominator EFI.

    I've switched from the HP EFI ECU to the Dominator ECU. Swapped turbo 350 to a 4L80E. I bought the harness to plug & play for the transmission, but which extra harness do I need to buy to hook up the proper outputs to the speedometer? I have J2A, J2B & J3 open. I'm fairly new to the Holley EFI stuff and have a professional lined up to tune the car, but I would like to have this hooked up ahead of time. Any help is greatly appreciated.
