What the heck is this?
I’m stumped - my 2016 Sprinter Citation has a threaded water line end and a power switch in the utility bay. Thor customer support says the threaded water line is for rinsing out the black tank, and has no idea what the power switch is for.
You can see the water line (with a black plug, to the left of the main water fill) and the black switch just above it in the attached picture. The switch looks like it would control a light, but there isn’t one.
I’m a little cautious about filling water into the mystery line as it looks like it’s connected to my water input...and if this is to flush out the black tank, then that’s too weird!
Any information would be much appreciated!
