I found my shop bought cable wouldn't work until I'd snipped all the extraneous wires. I think it only used 3 wires in the end, as per the MBE lead diagram (search on poast posts.... )
Cerealsurfer, If you just need the ECU software shoot me a mail through my profile as I've temporarily put it on one of sites. If not and you can wait Deans offer sounds good. What else is on the CD Dean? I have a CD with Parts manual and some of the workshop manual.
