    if you look on your alternator loom it will have a 2 or 4 pin plug on the end, 1 of these is the blue trigger wire for the battery, 1 is the DFM pin you're looking for and tyhe other 2 if present can be ignored as they'll be for aircon. if you dont have the alternator loom then bag yourself one from the scrappy and chop a good length of loom from the car side plug as well this will make it easier for you to tap it into your car :)

    ok so I found that and wired the dfm pin, where does the other go? (only a 2 pin plug)

    also i'm not getting anything to my fuel pump.... I get 12v at G2/G5 where my ecu ign + is connected but nothing to my fuel pump if its connected to E14 or but it does work if perm+ or G2/5. the car cranks but no start. Ecu relay clicks on key turn. Ecu earth is connected, coil earth is connected, what should I be checking next? sorry for all the questions! haven't even got to the oil sensors of clocks yet!!

    the charge wire goes to the blue spade on the lighting loom near the battery + cable

    for the fuel pump you need a 67, 80 or 167 fuel relay in slot 2 and the ecu relay trigger wire spliced to D/13. dont forget to add a fuse to slot 5! to test the pump relay socket and wiring pop a 17 or 18 relay in slot 2, this will bring the pump feed on with ignition all the time, fine for testing but not safe in the long run.

    I'll double check all that later on, It has a part no 321 906 059F relay, no number on it, and when i wire it so the fuel pump is on with ign (not through the relay) it still doesn't start, which makes me think the problem is with the ecu, coils or would the lack of clocks make a difference? does the ecu still look for the immob in the clocks?

    thats a kjet fuel relay so that'll probably be why, get shot of it and find the right one :)

    if it was the immobiliser the engine would fire for a few seconds then cut out

    Woo she starts! Cheers for the advice, relay was the answer. Where does the charge wire go to after that plug? the plug is no longer in my loom for some reason!

    it goes to C/2 on the lightign loom yellow plug. but if its easier for you you could run it in with the engien loom to D/4, or you an put it to the G spades #4 as well all those pins are linked to the battery warning light on dash :)

    the blue wire both runs the battery warnign light in the dash, and triggers your alternator to charge the battery properly :)

    right the LHD pedal for that ECU is 6Q1721503D, RHD is 1J2721503H. this is the later complete pedal module type :)

    pretty sure the remote mounted actuator 1J1721727D would still work fine with it too tho?

    Yes , it works fine. I saw already work in another car, but just wanted to know if the binding order is the same as the original.
