I haven't figured out how to post pics..but there's a large number of wires in the cabinet! Like 25! Is there a color scheme?
On top of the TC there is a little weird plug in thing with a rubber flappy cover. It's black, square, about 2 inches by 2 inches. It's near the front drivers side door. Could this be the solar prep plug? If so, what type of male plug end do I need to plug into the hole?
I did not find anything extra in the battery compartment except a little metal round cover that is caulked over. About 2 inch diameter, on the left side of the inner battery compartment. I did not peel it off to reveal anything inside.
I took pics but I will have to figure out how to post them.
