I found this via google:

John Deere

     * Bosch male and female BMW accessory plugs are available from BMW
dealers. I don�t have the BMW part number nor the exact prices. A
simpler and much cheaper Bosch accessory socket is available from John
Deere dealers for about $9. In fact John Deere apparently has two female
sockets available, with the AL25073 part being mostly plastic and
cheaper , while the MG82002966 part is made with more metal and appears
to be more durable. I've used the AL25073, and it's Ok, but just Ok. The
Hella female socket (in my experience) grips the male part much more
securely than the John Deere / Bosch AL25073 does. John Deere part
numbers: Female socket: MG82002966, Female socket: AL25073, Male plug:
RE11344.
