I've been peeling the wiring onion a little bit more. The lights ground to
the trailer, and the ground wire from the plug to the belly panel (under the
water tank) is good, but the ground wire itself does not seem to connect to
the trailer. So here is the question: does anyone know where in the
trailer the ground wire (white) attaches to ground. The wire snakes back
from the belly panel into darkness .... Also, I'm assuming that the
ground wire from the wiring harness is completely separate from the inside
electrical system - is that right?
Again, thank you!
Christian
