    PNP Adapter Harness Wiring for M50, M52, S50, & S52 (And MORE!)

    LIFETIME warranty on workmanship with proof of purchase.
    Want to get your swap finished quicker? These adapters will save you a lot of headaches and hassle.

    We now offer an A/C solution for the M52TU, M54, S54, M62, M62TU, and S62 swaps.
    These can be prewired into the harness adapter, or added on separately if you already have a harness adapter.
    Message or Email us for more information.

    You can reach us at: sales@redline-motorsport.com

    All additional options are included in the prices. All standard relays and fuses are included (With an exception of the S54/S62 EKP Module)

    NLA connectors such as (E12/E21/E30 Square C101, C104, Z3M S54) will be high quality reproductions to allow for a simple Plug-and-Play solution. If we have a used connector available, we will use those before the reproduction style. No extra rewiring will be required.

    Benchflash harness for MS42, MS43, MS45, ME7.2, MSS54/HP, and MSS52
    $85.00

    We do offer an ECU benchflash harness to reflash your DME outside of the car.
    It will come with instructions and links for the necessary software.
    It is intended to be used with any 12v power supply. It is suggested to use one that only reaches 5 amps maximum. Otherwise, I suggest to add a fuse to the (+) terminal on the benchflash harness.
    You will just need to get an INPA K+DCAN cable and/or Galletto 1260 cable. These options are explained in the included instructions.



    Radiator/Auxiliary fan wiring is now available. This wiring is intended for the E30, E36, or E46 original auxiliary fans.
    The E30 and E36 fans will need to be used with the 88/80c radiator temperature sensor, part# 61318361787.
    If you have another option in mind, contact us to see if we can provide a harness for your setup.


    For pictures, please refer to the website. We are continuously adding to our website.

    We can make conversion kits for the E9, 1602, 2002, E12, E21, E24, E28, E30, E34, E36, Z3, E39, and E46 chassis.

      Do only the 'e' models require that you run the tach, mpg, and speed signal through the harness?

        I'll definitely jump on this when I'm a little closer to getting my m52 installed.
        Do I need to send you the harnesses or do you use your own?

          No, there are actually some 87 "i" models that use them as well. An easy way to tell is if you see a 3 pin connector (c104) in your glovebox area. Pin 1 should be black, pin 2 should be red/green, and pin 3 should be yellow/white. If you have this connector, then you will need the extra wires.

          The extra wires are included with the harness (if your model requires it)

            Excellent, just send me a message whenever you are ready.

            If you want your harness repinned, then you would need to send your own harness.
            If you would just like the adapter harness (like the pictures above), then you wouldnt need to send me your harness.
