Mercedes C3 mux <> 38 pin diagnostic cable

[Mjolinor]

Does anyone have the pinouts for the mux end of this cable?

Mine broke a pin and when I opened the plug the wires came off.

I am not buying a cable that is used once every blue moon.

Is there anyone local can lend me one to buzz out so I can make mine whole again?

Cheers.

Hi
1-38 pins are connect to A-q ( 1 to A, 2 to B ,.. 23 to Z, 24 to a, ..., 38 to q)

Cable coding pins connect y to 1, z to 1, AA to 1, BB to 3, CC to 1

It doesn't work. Have checked that the pins are connecting OK from the C3 plug to the loom on the car and they are OK but DAS says something about circuit 31 being up the spout.

Hmm, it didn't work because there were broken ones in the RS232 lead as well. The pinout is good.
