    The "Stefan Borch" method works for all of our fleet (e32/e34/e36). You've got the right pins, but the timing & sequence is critical for some cars:

    Someone on bimmerforums left a little note on one of the service interval reset threads that I found very useful. If you don't have a wire already handy that you plan on using, an RCA cable (as in the red, white, yellow cables to connect components to the TV) works excellent to connect the pins temporarily.

    I actually did it this morning!

    I think I have one of these laying around, if you need it you can have it for shipping costs
