UPDATE!
I finally got around to pulling the seat off and indeed, the brake PCV (Proportional Control Valve) under the seat has been removed, and an adapter used to transition from a solid to a flexible stainless braided line.
When this was done, the brake line was bent a bit to make the transition, and caused the wire harness to be pushed closer to the rear exhaust port. :xzqxz:Burned the outer cover (electrical tape? ) off, but a CLOSE inspection shows no wire damage. Whew!
Also, taking the axle apart to have it sent out of state for repair, I established the oil level was much lower than the original fill plug. The fluid level is very clear to see on the inside of the back cover, so I am going to drill a hole and use the rubber plug Jack suggested. THANKS again for that idea!
