    basically the same as mk2/3 golf swap yeah, the passat has the ce2 fusebox and the subframe mounting points are in the same place though the subframe itself is different. if its a manual then all the brackets swap right over job done

    So it would be a point of getting the engine and dropping it onto the mounts then fiddle with the wiring or find a plug and play one lol wonder if the 1z tdi box will fit too lol

    yeah the box will bolt right on as well, peeps often like the diesel ratios for a 20v

    you could prob fit a mk4 pump in the diesel tank if its liek a mk3, just need to adapt the level board to work on the clocks. either swp the level assy over or desolder 2 wires and swap apparently. tank will need a proper good clean obv lol

    pin 1 on the T10W from all accounts is used on earlier ecu to put them into 'flash mode' or similar, you put 12v on this pin when trying to access it thru the vagcom port when working on the flash data. for the average user this can be ignored, but if you're worried about it just be sure to run it inside the cabin so it can be accessed if need be, or make a note of where the cut end is inside the engine bay so you can unwrap the harness to get to it

    and yes dbc = drive by cable e.g. AGU and DBW = drive by wire e.g. aum, auq, bam etc

    Hi

    Ive build the 1.8T 2-v AUM into my Vanagon but forgot about the diagnostics wiring and plug... I have all wiring but the part that goes in the "cluster"

    Can i use the above mentioned K-Line and the +/- (3 wires) to diagnose my setup?

    look at the ecu relay notes further down the guide, what you do with it depends on what you plan to do about ecu/coil power. I recommend adding an ecu relay above the fusebox with a 15a fused live to feed both the ecu t6/1 and the coilpack live on the T10/14a plug :)

    Thanks for you help john,so i need to wire in a relay like this
    DBC/Non-earth switched ECU relay type:
    30 - permanent live (spade P CE1, or Y CE2)
    85 - earth
    86 - ignition live (D/2 or D/7, or G spade 2 or 5 CE1, G1/4 or G2/4 or D/8, 9 or 11 CE2)
    87 - power for ECU/Coilpacks (t6/1 and t10a/8)

    thats it, you have the CE2 fusebox so look at G1/4, G2/4 or the D plug feeds. put a 15a fuse inline with the 30 pin as well

    Thanks john your a legend. You make the loom for my conversion about 3-4 years back,and I don't remember seeing the extra relay. Will a number 53 relay do the job?

    I probably wired it up to use the stock ecu relay then, try a 30 or 32 in slot 3 :)

    Just a quick question;

    My mk2 originally had the Auq engine fitted when I did the conversion, but now have an amk Ecu / engine to go in.
    What I'm wondering is whether it can be a case of just swapping the Ecu or if I'll need to do any wiring changes?

    The only thing I know I'll have to add is the exhaust gas temp sensor wiring as the Auq doesn't have one.

    Also is there a good site that has wiring diagrams?

    Thanks!

    basically the same ecu pinout, as you say you need to add the EGT sensor. pretty simple really:
    1 - 61
    2 - 50 (shared with PAS pressure switch if it had one)
    3 - tapped to fuel pump live (same wire as MAF pin 2 is factory)

    all the spare ecu slots have empty pins inside on the DBW ecu, plus you'll probably have a ton of spare cut wires from deleted stuff you coul use instead :thumbup:

    see my signature link for diagrams. I have 'a few' the one you want is a3amkaryauqarxaum.pdf :)

    Thanks John :thumbup:

    Just had a look, and the amk PDF isn't working. Don't know if it's just me, or somethings up with the PDf itself.
