Extra power connections near tank sensors?
I've got a 2017 Thor Freedom Elite 22FE and while fueling up the other day I noticed a wire dangling down near where the black & grey water tanks are located. I assumed the sensor wire came loose and went about repairing it when I got home.
Except now that I've been under the chassis, it's not the sensor wiring at all. Going to each tank is a flexible black wire tubing with 4 wires inside: two end in a dual-crimp (red) connector which is hooked up to the tank sensor wiring, the other is another dual crimp connector (blue) without anything plugged in -- This is what was hanging down. The grey water tank has exactly the same setup: one pair to the tank sensor, the other is just bundled up with a zip tie.
At first glance I thought these blue connectors should be connected to eachother but that doesn't seem to be the case, are these just an extra power source for something? It's a bit too tight to identify where they ultimately lead as they go into the bundle of wiring for everything else underneath.
