    Hi all,
    Can anyone help me with wiring pinouts on grey plug that went into fusebox originally from audi a3 1.8t automatic (1999 car)
    I know this plug feeds gearbox ecu but need to know what needs to be connected for mk2 golf conversion. Thanks Toby

    Hi , sorry its staying automatic in the mk2 so I need to use the feeds on the grey plug to power gearbox ecu. What I need to know is what I can link those 10 wires to on the mk2
    Or even what they do so I can work out what I need to keep from that grey plug.

    T10b - grey:
    1 - blk/grn - ignition live
    2 - red/blk - connect to brake light switch black/red
    3 - gry/wht - diagnostics
    4 - brn - starter inhibitor relay pin 7/31 (earthed in engine harness somewhere, suspect with main ecu earth ring terminal near ecu)
    5 - red/pur - permanent live
    6 - yel/blu - starter inhibitor relay pin 9/S7
    7 - red - J189 'auto check system' pin 6 (assume some kind of check light?)
    8 - red/yel - starter inhibitor relay pin 1/S1
    9 - red/gry - starter inhibitor relay pin 3/PN
    10 - brn/blu - selector lock solenoid pin 2 and selector light unit pin 1

    I've put the diagram in my signature link, 8l1autoecu.pdf
