Thread: Holley Analog TBI

    Default Holley Analog TBI

    Hi there. I have an analog TBI I'd like to use on my 345 International Scout, but have no wiring instructions. Can anyone help? Also, I heard you can just swap out the analog ECU for the digital one. Is that true? Many thanks.

    Do you have the Holley part number for this?
    Is this a 2 or 4 barrel Pro-Jection TBI system?
    More information required.

    No part number, but ECU is clear anodized, no ribs or heat sinks.
    Black plastic end caps, one end has 5 or so adjustable pots.
    What I need to know most of all, is if the wiring is the same as 2D digital.
    I have read it is, but am doubtful.
    When I get home, I'll look again for part number.
    Many thanks for your help. Tim

    So this is a 2 barrel Pro-Jection TBI system?

    If so, maybe one of these manuals will help you:
