    M42 DME harness pinout?

    I'm going to be wiring up megasquirt on my 318is soon in preparation for turbo, but I can't seem to find the pinout or wiring diagrams for the 55-pin connector that plugs into the DME (175-label). I can find the ones for M20 cars, but I'd assume the M42 DME has a few differences. If anyone can post or link it here, that would be great.
