Hi volks,

The socket in question is a 12V accessory socket.  The plugs can be
purchased from your local BMW motorcycle dealer or by mail order from
California BMW in Mountain View CA.  I don't have the BMW p/n but here's a
note from Jeff Dean:

Subject: BMW: elec. plugs
Thanks to all of you who responded to me request for info. regarding
obtaining BMW electrical plugs and sockets from John Deere. The parts
numbers were given to me immediately:

For the "50" series John Deere farm tractor:

Accessory Plug -- RE11344
Accessory Socket -- AL25073
I checked locally at a John Deere implement company and found plugs for
$6.59 and sockets for $3.40--both in stock. I go out tonight to see if they
are a match for BMWs' items. I suppose they'll be green!

This setup is commonly used to wire a dc source for heated vests/gloves for
motofolk.
