Anybody ??

Let me see if I can help. Using the Mercedes service CD, looks like there are two 12-pin plugs, but only one has 10 wires. This applies to USA and Japan models up to 1982 with the 8-cylinder engine:

1st connector:
Pin 1 = yellow/red
Pin 2 = black/blue
Pin 3 = brown
Pin 4 = brown/white
Pin 5 = black/green
Pin 6 = black/red
Pin 7 = yellow
Pin 8 = empty
Pin 9 = black/yellow
Pin 10 = blue/red
Pin 11 = empty
Pin 12 = yellow/black

Second connector:
Pin 1 = black/purple
Pin 2 = brown
Pin 3 = black/white
Pin 4 = black/blue/yellow
Pin 5 = black/green/white
Pin 6 = black/yellow/red
Pin 7 = brown/blue
Pin 8 = yellow/green
Pin 9 = brown/black
Pin 10 = black/red/purple
Pin 11 = blue/purple
Pin 12 = black/red

I would recommend that if you are going to do much work on your car, you should buy a service manual CD. Lots of info packed into the CD.

Disclaimer: I have did my best to double-check the colors with the manual, but cannot guarantee 100% accuracy.

Good Luck.
