    Can anyone identify for me the various pins on the plug that connects to the back of my instrument module. My '83 R100RS needs a little electrical sorting out, this would be a big help.

    It's in the owner's manual if you have one.

    The data is in the manual, and various wiring diagrams on the net. I think snowbum has a number of them on his site.

    What are the problems you're having?

    From my experience, the problem is often high resistance at the pins leading into the cluster where they join the copper traces.

    In the wiring diagram, you'll see numbers which relate to the ones on the big square rubber plug - there are no numbers on the light board itself.
