Thread: Terminator EFI - oil pressure on Holley digital gauge?

  1. #1

    Default Terminator EFI - oil pressure on Holley digital gauge?

    Looking to display oil pressure via Terminator EFI on a Holley Universal Gauge. A quick conversation with Holley tech support indicated that's not really possible by default. The suggestion was to use the fuel pressure plug on the harness, and just know that's it's showing me oil pressure. I suppose I'd use the Holley 554-102 transducer, wire in another universal gauge in the chain, and set the gauge input to be 022, and set my gauge ranges where I want them? Thoughts?

    Yes, you can have the fuel & oil pressure transducers connected to the Terminator EFI.

    The Terminator EFI main harness doesn't have that oil transducer harness populated.
    You have to wire the Signal into pin A20 on the P1A ECU connector (EFI main harness).
    Power - A26-P1A "Sensor +5V Sensor Ref Out", Ground - A18-P1A "Sensor Ground Out"
    Look at how the fuel pressure transducer is wired into the P1A ECU connector:

    OK, so do I need to physically splice into the wires going to A18 and A26? Or somehow use pins or an adapter? Also, is there some sort of Holley pin kit or standard pin I can get to add the signal wire to the plug?

    Just splice into the +5V & ground wires.
