Where is the other end of this wire I wonder

[EdC]

My new to me 2011 R1200RT came with a 14 year old nav system in a mount above the speedo etc. I decided it should come out, so I unmounted the mount and detached the wire from the nav unit and discovered the wire plunges deep into the bowels of the machine. But not to the battery directly, so there must be a place somewhere in the wiring harness where it is wired in.

So....how much am I going to have to remove, probably, to get to this? Short term I can wrap the wire to prevent shorts and tie it off to keep it from dangling, but long term I want to take the wire out of the system entirely. Any thoughts?

You will find the connecting plug at the bottom of the headstock
