What is this electrical plug (under dash)

[BGB]

Taking my time off from work to start cleaning up a mess of previous repairs.

 

found this plug not connected to anything and tucked away near the column. I’m sure you all can point me in the right direction.

Clock?

It does look like a clock plug. Probably for the long ago disconnected door buzzer.

Clock? Door buzzer? These items seem pretty luxurious ha

 

my car is 1970 and to my knowledge never came with a clock

All US spec 2002s came with a tach--it was one of the "non-optional options" that Max Hoffman ordered for all US-bound cars, (along with vinyl upholstery, bumper guards, radial tires and a chrome exhaust pipe tip).  Otherwise you got a clock (also if you had an automatic).  Were you to examine the back side of your instrument cluster, behind the tach you'd see a rubber plug; remove the plug and you'll see the male terminals that mate with the plug you pictured.  That's for the clock.

Ah very interesting Mike! Thanks for this info I’ll have to check this out

For a clock you'll find one wire always hot, a ground wire (brown), and a wire that comes on with the head/dash lights and responds to the dimmer, the buzzer just has 2 wires a sometimes hot wire and a ground wire.

Here's what to look for on your instrument pod. Wire colors may be different for earlier cars.

Gimme your model year and I'll give you a definitive answer.  Best guess so far is this '74 connector, but your pic looks much closer to brown/yellow than brown/green. . .

I for one DON'T think that's the clock connector, looks more like one of the connectors going up to the fasten seat belt pod IMO.

 

EDIT: Nuts, now I see where you said 1970, but haven't turned up anything like that on my '70 diagram. . . hmm. . bmw2002-usa-early.pdf

My car is a late 1970 build but titled as a 71 if that makes any difference

Early cars don't have the same clock connector as shown in John 76's picture--it's more like a black version of the tach connection in that same picture, and it's for the clock.  Those early cars, like BGB's '70 and my '69 have a separate tach wire that doesn't appear to be integrated into the rest of the wiring harness.  At least that's the way I remember it last time I had the instrument cluster out of my '69.

Found the pins right behind the rubber plug as Mike described
