Does anyone know where i can find out what each pin on the car side of the c101 does?

If you have a look at my M50 non-starting thread page 1,a link has been posted to a site with wiring diagrams.The link initialy comes up in (I think!!) Russian,but you can find an English version as well.You should be able to find the information there.

The Russian wiring diagrams don't actually give the pin numbers.
This should help. It's actually the details to connect a M50 loom to an E30 plug, but the info you want is in there:

Thanks guys!

Is pin 20 engine speed the tachometer?

Jhonno, i am after the info for wiring my vauxhall engine into my rally car so hopefully i won't have the same problem

[Jhonno]

You may do if you wire a C101 on the end and it earths it..

Better safe than sorry

Pin 9 (black) is engine speed.
Pin 20 was formerly the earth for a two pin engine temperature sensor, and latterly the power feed for ABS.
A couple of the wires are a different colour on the car side of the plug.
