Extra wires to battery

[DC8Captain]

Hi Folks,

On my Jay Flight TT there are two wires coming out of the TT wiring harness that CW hooked up to the battery when I took delivery. I asked the PDI person what they went to and why they were not part of the TT power supplied by the normal battery cables. He didn't know and neither did the shop manager. They are on all the TT's. The nice folks at Jayco Customer Service didn't know either.

Here is a picture:

Why don't dealers and Jayco know the answers to stuff like this?

Someone else post about this a couple months ago. They tracked it down to the solar prep. If you have a multimeter you could verify this fairly easily.
