Benchflash harness for MS42, MS43, MSS54/HP, and MSS52
$45 shipped

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 a Galletto 1260 cable and/or the INPA K+DCAN cable. These options are explained in the included instructions.


For pictures, please refer to the website. We are continuously adding to our website.
http://www.redline-motorsport.com

We can make some wiring kits for the E46 and E39 chassis.
We can make wiring kits for the 1602 and 2002 chassis.

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

Send a message via AIM to schmidty
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.
