    Paul, Is this a 1.8T?
    What is your spark plug/coil setup like? I have 4 wires on my 4Motion. 2 earths, 1 Live and 1 trigger.
    Check that you have 12V on the Blue/Yellow at the MAF.

    Hmm, Why wont my G1/8 work then[xx(]

    Should i really be running T14A/7 to G1/7? I currently have it as a chassis earth.

    Edit, Hang on! G1/7is not an earth anyway! G1/07, Overrun Cutoff Valve, G60 Difigant ECU Power, Overrun Cutoff Relay, ECU Relay Brown/White (Carb only) or Black/White (G60 only)

    You should not be running an earth to that pin.

    My relay stuff is fine, using a 109 though as I get a fault code with a 32.
    Dont seem to get power on G1/8 though for some reason. I will have to check the fusebox over.

    I have and it works fine like that, This is how it currently is running. It it would be to use G1/8 though as it is fused.

    noooooo! T14a/7 is the main earth for all the coilpacks/spark units.

    G1/7 is a reference live feed from the 30 relay, or on the vr6 its the earth trigger for the ecu relay. its never an earth for anything! no wonder it didnt work :lol:

    where did you see T14a/7 goes to G1/7?

    just to add the fault code with 30/32 relay isnt an issue, the only reason i recommend 30 relay is its cheaper from vw and easier to get in a pinch from the scrappy :)

    its when you realise this whole forum is a product of your damaged psyche that you should worry :thumbup:

    on the mk3 the speedo sender gets power from the coil live to G1/4, G2/4 would be ok too or the ecu/ign live feeds you already have to the T14 plug. you could tap into the ign live pin on the reverse switch for an easy location as well
