'12 R1200GS Does anyone know what this wire is?

I just got a new-to-me R1200GS. Does anyone know what this wire is? It hangs loose in the space behind the oil radiator, beside the top of the left (seated on the bike) fork tube.

Previous owner had a GPS? Looks like the aux power lead that if not used is secured to frame in that location.

Hmm, that could be. My older Garmin has a much smaller wire but I'm not familiar with the newer ones. How bout tire pressure sensor? I see in the service papers I received with the bike that a sensor was installed but I don't see the data on the computer... unless I just don't know how to bring up the data. I assume it should show up as I scroll through with the info button.

Perhaps it connects to an auxiliary power port.

It's the GPS connector. Provides ground, switched +12V, and a speed signal. The matching plug is part 83300413585 if you want to tap into it without a BMW GPS. It is on the same circuit as the accessory socket(s). Tape it off to keep it dry you are not using it.

Thanks. That would be handy. Do other GPS units use the speed signal or would it just be to tap the power?

Just to tap the power. As far as I know, the speed signal is not used by any GPS other than the BMW branded Navigator series. Since the NAV units also work without that signal, I really don't know why that wire is even present.

On the bike side of the connector the wiring colors are as follows:
(1) Brown = ground
(2) Blue/Green = Speed Pulse
(3) Red/White = 12V

The matching plug (also known as a repair connector) comes with three yellow wire leads attached. You can identify the yellow wires using the numbers(1,2,3) molded into the plastic plug next to the pins.
