38xx wiring at 12v circuit breaker panel-gctid812036

[Pcpete]

Don't you just hate it when there's a wire not connected and you can't see where it should? I was replacing all of my engine control cables and, as part of gaining access at the lower helm, I opened the engine switch and circuit breaker panel. The one with all the pop out breakers. At some point I noticed a brown wire that wasn't connected to anything. It didn't have any marks like it had been connected to a male connector, nor could I find a male connector that looked like it was suddenly missing a connector. It's in the area of a spotlight breaker, but the spotlight works, mostly. There are other brown wire that are connected to other items, but I'm not sure what. I thought this panel would show up on one of the schematics but, as usual, I'm either wrong or can't see it. Any ideas?
