    The oldtimers is settin' in . . . . . .

    I took things apart in May before a major project and I have forgotten about a set of electrical contacts.
    On my 1993 R100RT there is a bright blue recepticle with five male contacts. There is room for six contacts but one is missing. This recepticle has no cover and is on the right side of the m/c. It is located behind the headlight and start relays. What plugs into this recepticle?
    Thanks,

    Nothing -- I can't remember whether it should have a cover, but I recall that it is primarily there for Authority versions of the RT to power lights, etc.

    Campbell, do you have heated grips??


    I seem to recall when I bought my bike, I installed a factory kit
    to upgrade to heated grips. And that blue plug was waiting for
    me, just had to plug in the harness from the kit.

    Same answer as Mark, extra stuff you don't have...

    Maybe a different blue plug? My '94 RT's heated grips were connected elsewhere (BMW kit). The empty blue plug I'm referring to is back nearly to the end of the frame backbone.

    My 1985 R80RT has that same connector block. It had a plastic cover which went somewhere without me a few years back. When the bike was new, someone told me that it was for a factory diagnostic device, but I'm inclined to doubt that. On the other hand, I've just been too lazy to trace the wires to see if the connector appears to have been designed to power something or to diagnose something.

    At any rate, I've never used it or seen it used for anything. I would not worry about it.

    That rings a bell -- I remember at gray, flat-topped cover for the blue plug.

    I did -- the schematic I reviewed had references to Authority equipment.

    I used the 12V terminal in the plug to power some long-forgotton piece of electronics (a helmet speaker for listening to mp3's from a GPS, IIRC) -- a convenient source of ignition-switched 12V power.

    Given that at least one of the terminals is "live" when the ignition is on, the "prudent" thing to do would be to provides some sort of cover/plug/weather protection. That said, given where the plug is, it would take quite a monsoon, or the routing of thinly-insulated wires directly over the blue plug for any real problem to ever occur. Probably the easiest thing to do is wrap electrician's tape around it, and then forget it.
