Thread: 553-104 handheld to 3.5” TSLCD?

    Default 553-104 handheld to 3.5” TSLCD?

    Hello. I have a Holley Avenger with the original 553-104 handheld controller. The controller screen has faded and I can’t see it. Can I upgrade to a 3.5” touchscreen and still use the Wizard? If so, what parts do I need to make this work? Thanks Steve

    Looks like I have a screen I can use if it’s the correct one? The part number on the back is 200R613A. If this will work what adapter harness can I buy?

    I have the Terminator handheld with V4 in it. I clipped the connector off it to make the power & CAN Bus connection to the early Holley TPI harness I have, but it does work. PM me if you want it and I can help you out, not trying to make money, just clear out unused parts and help a fellow gear head out. It's guaranteed to work or money back, just clip your connector off and put on this one, wrap in black heat shrink and it will look like factory.
