    yes, one is a switch, one is 5v, one is ground and one is a signal. do you have the wiring diagrams?

    Light green/white - signal
    Light green/red - 5v
    black/brown - ground

      kinda. i have a wiring diagram for the automatic egt and the manual egt. and i have a halfass megasquirt diagram. the megasquirt diagram shows me enough. but the auto egt diagram only shows the tps wire colors. it dont show which is the 5vref, sig, nor ground.

        i found this slight mumbojumbo in the halteck sticky

        +5 Volt (RED / GREEN) +5 Volt (ORANGE)
        Throttle % (GREEN / WHITE) Throttle % (GREEN)
        Ground (BLACK / BROWN) Ground (BLACK)
        Idle Switch (RED / WHITE) Ground (BLACK)


        so where do i run the idle switch then?

          You don't use or need the idle switch
