    Awesome to find the opposite connector to keep it OEM. Mine just arrived today.

     

    I’m finally going to tackle this at the weekend. I’ll be wiring the first stage to one fan, 2nd stage will run both (with a diode so the first stage doesn’t run both) and 3rd stage will instead be wired to an OEM de-mister dash switch and will also run both fans.

    Hi there,

     

    I'm currently rebuilding the bottom end of my ABV motor and it looks to have no ovalisation, which is good news. This means I'm looking for some new OE spec piston rings.

     

    Can people recommend Mahle? The price of OE parts seems rather excessive. Does anybody also know who the manufacturers of the OE parts is?

     

    Thanks, Phil.

    Hi there,

     

    As per the title; I'm looking for a 4-pin VR6 MAF as I'm converting my engine to coilpack and have the 4-pin ECU and loom.

     

    Anybody have one kicking around?

     

    Best, Phil.

    Update, it looks the original brown/white wire has been replaced with the brown/red wire on the yellow two-pin connector in the new loom, which goes to the aux water pump in both instances (similar to what Swiftkid said). The black/red wire w/single red connector on the old loom has been combined into the yellow two-pin connector on the new loom, but is for the yellow coolant temperature plug in both instances.

     

    Was a bit of a mission tracing these as the pinouts on the 42-pin engine loom connector have very different pinouts between the two era of looms!

     

    To confirm if anyone comes here from google, the early loom is part number 536 971 072 AS and the late is 536 971 072 DJ.

     

    Now I've just got to change the connectors for those two wires and also source a new MAF sensor, as the late one also uses a 4-pin, which I believe is hot-film instead of the original 5-pin hot-wire sensor.

     

    Cheers, Phil.

    Haha, no worries.

     

    Unfortunately I forgot to get a picture of the part number of the ECU before I fitted it, but I'll get it at the weekend.

     

    After tracing the wire and consulting the Bentley manual, it looks like the violet/white wire is an MPG sender to T28/26 on the instrument cluster. Now, my car never had that, which the Bentley manual confirms, so not entirely sure if it's required. Probably safe to leave it disconnected for now though.

     

    Interesting about the yellow two pin connector, I found some very similar wires which do what you say in the Bentley manual, but don't have the same colours. Perhaps that's not been updated on their part, or is different between LHD/RHD vehicles?

     

    It also looks like the red/yellow wires with red connectors are the same between looms, just with a slightly different connector. The black/yellow wire runs through to a single connector at the other end of the loom, which wasn't present on my original loom at all, I'm having trouble finding out what it's for. Any idea Swiftkid?

    Hi folks,

     

    I'm in the process of swapping my '92 dizzy VR6 motor for a '94 coilpack motor, ECU and '95 engine loom. I've just extracted the original loom and was comparing the two, which I believed would be plug and play into the fusebox, and there's a couple of differences (it's never as easy as you think!).

     

    I essentially have no idea what I'm doing with this kind of thing, so after some searching I found this page which seems to list the changes http://www.a2resource.com/electrical/management/motronicvr6aba.html, which look to relate to having the 94+ loom. However, this leaves me stumped with how I should connect them to the fusebox and whether they need to be spliced into the old connectors or be left disconnected :scratch:

     

    Differences from dizzy loom to '95 coilpack loom:

     

    - One of the '95 "G" plugs has a couple of extra wires going into it

    - Different red connector on the yellow/red wire

    - Extra single pin yellow connector with yellow/black wire

    - Extra single pin black connector with violet/white wire

    - Extra double pin yellow connector with black/red & brown/red wires

    - No white connector with brown/white wire

    - No red connector with black/red wire

     

    I wonder if the yellow connector (black/red & brown/red wires) are an amalgamation of the earlier loom's white connector and red connector (black/red wire), which I believe are grounds?

     

    Here are some pics!

    Any help would be much appreciated.

     

    Thanks, Phil.
