What on earth......

....Is this mess that some absolute butcher left under the left hand tray?
Any ideas guys?

Looks to me like a hack job on a Garmin Zumo wire harness. A PO probably wanted to remove the mount but didn't want to go to the effort of properly disconnecting the harness.

In doing so, he destroyed the part of the harness that he kept as well as the portion that is left on the bike.

There is nothing worst than real evidence of a real hack. There is nothing wrong with cutting unused wires; however, sometimes when cutting a harness like that it can leave the ends touching each other. A better way is to cut the harness leaving wire to work with, then cut the individual wires, and secure their ends with shrink wrap or electrical tape.

Correct. It's definitely not helping with my issues.
