I just finished cleaning up all the wiring in my battery compartment. I have identified all wiring except for one; a 16ga blue wire coming from the belly. Keystone must have thought it was important, they had it connected directly to 12V; not going through a breaker. I thought it was the CO detector, but it's not. With it disconnected, I can't find anything that does not work.

Any ideas?
