M40 to M50 swap

[eastinthewest]

Someone has to have done this before. What I cut off the old harness does not appear to be a c101. Suggestions?

Does anyone know where to find the wire diagram of the plug off the M40 harness?

What year is your car? I'm doing something similiar, and my car certainly had the c101. Maybe you are confusing it with the diagnostic port?

For reference my car is a '93 touring

M40 prob has the early square C101...

[eastinthewest]

91 Touring. You might be right. I'll take pictures later and upload what I have.

[eastinthewest]

yea it's definately *not* the square C101

My 93 Touring had a round connector on the m40

DUDE! I think you're right. So does the C101 have the pins or the Female end?

[eastinthewest]

still having the same issue though. The colors from the diagrams are not matching up to my harnesses. Might be because I'm in Germany and the car is German spec

you may have to just trace everything out... engine side c101 is male, body side is female.
