  • Help with chassis plug

    Hi fellas,

    Can anyone help identify what pins are what, the guides on here and the saxo forum say the later model 3 plug ecus used 3 different pin configs but the one i've is completely different.

    its a 1.1 independence 2000 model. Any help or information would be much appreciated.

    Cheers
    Kieran

    There are only 2 pin configs for 3 plug ecu models.

    crossover loom and non crossover loom

    Looks very much like a later style 3 plug to me. your plug isn't completely different.

    The pins are numbered on the guide left to right, starting at the top. The top left most is no.1 and the bottom right most pin is 37.

    A multimeter is your friend.

      Ah okay thanks ill spend some time today going through it see if i can't make some progress ID'ing the pins not on the guide.

      The guide says that the later 3 plug models this should be the pin out:

        Try this one. obviously being the 1.1 it won't have the wiring for the oil level and coolant gauges.

        Early 3-Plug ECU Chassis Plug (Mk2 saxos & S2 106):

        1. CM10E/CC2 - Ignition Live
        2. CH07A/C075 - Reverse
        3. 100 - Starter
        4. 822 - Immobiliser
        5. 820 - Immobiliser
        6. 2210/220 - Reverse
        7. 425/426/429 - Rev Counter
        8. 410 - Oil Pressure Red Light
        9. 1072/1071 - Alternator Warning Light
        10. 414 - Oil Level
        11. 415 - Oil Level
        12. 821 - Immobiliser
        13. 465 - Speedo
        14. 140 - Diagnostic Wire
        15. 141 - Diagnostic Wire
        16. 400 - Coolant Light
        17. 401 - Coolant Gauge
        18. 480 - Engine Management Warning Light
        19. Blank
        20. 411 - Oil Temperature
        ---------
        34. 124/120 - Fuel Pump Live
        35. 123 - Lambda Sensor Live (Note: this needs bridging with an ignition live if fitting engine to a later 3plug model)
