Solar wires to front slide

[jcwilde1]

I've been trying to read through the forum but haven't quite found what I am looking for. Does anyone have a link or information about the wire path if your battery is in the front? We have a 2922KS and I'm getting ready to mount two 100 watt panels and the slide out part is confusing me, my batteries and mppt will be below the couch in the front.

Also what would be a good spot for a shut off on this model? It would be great to have a shut off on the outside. Thanks!
