    looking around the board, i couldn't find a complete chart on this, just thought it should be here...enjoy

    ca18de harness setup:

    101 102 103 104 105 106 107 108|01 02 03 04 05 06|13 14 15 16 17 18 19 20 21 22|33 34 35 36 37 38 39 40|

    54 34 red ==TPS idle
    55 --------------------- Ambient Air Temp Sensor None on Exa
    56 --------------------- Auto control. Auto? Yeah right!
    57 44 white/blue ==TPS FULL!!!! the way it should always be!!!!!!!!!
    58 46 black/red ==Battery unswitched
    59 39 blue ==Battery from ECCS relay
    60 48 black ==Ground
    101 101 white/shield ==Injector 1

    111 102 orange ==Fuel Pressure Reg.
    112 112 white/blue ==Injector 4
    115 ----------- Heater output for O2 sensor Exa's only have one wire for O2 sensor.
    116 116 black ==Injector Ground

    and here's the vacuum diagram for the kn13 ca18de. i got this from a nissan dealer so all the part numbers are also there. notice the highlighter, i've used this a couple times.
