Please Help... 10awg mystery extra wires

#1
I just bought a 2001 Komfort 24fs fifth wheel, I am fairly handy, I had to put in a new floor in the slide out, anyway I want to add solar, I found a red and wht. 10ga wire "cut ends" in a loom by itself next to the battery compartment in the basement, I also found 2 of the same under the sink just wires in a loom and cut ends, they do not go to the 12v system or ground, they do not go to each other unless I am missing a cut off switch somewhere, my question is did Komfort wire for future inverter / solar? if so where do they go? any help is appreciated.
PS, I did check continuity for all wires mentioned to each other and ground and for voltage.
