Thread: Holley CAN Bus Gauges

    Default Holley CAN Bus Gauges

    Hello everyone. '69 Chevelle with LS1/4L60E and Terminator X here. I'd like to hook a set of Holley CAN Bus gauges, and retain the handheld. So really two questions:
    1) The installation manual section 10.3.15 says, "The handheld plugs directly into the main harness at either connector labelled CAN". However, there seems to be only one CAN connector on the main harness. Where is the other one as I could not find it?
    2) I need to use Holley P/N 554-130 to interface the Holley CAN gauges, but then to which source or wire should the black, white & red wires of 554-130 be spliced into the Terminator X harness?
    Thanks, Patrick

    The Terminator X main harness only has one CAN Bus connector.

    The new CAN Bus wiring has 4-wire connectors. +12V, Ground, CAN High & CAN Low.

    @Patrick777: The 554-130 is a CAN Bus converter for the gauges. It converts a one-wire digital signal into a two-wire CAN signal.
    You plug the black wire into the ECU J1-A15 as stated in the instructions, then the other two wires are just a switched +12V & standard ground. -Greg
