Ameri-Lite 274QB "Solar Ready Pre-Wired", where are the pre-wired cables?

[[email protected]]

My Ameri-Lite 274QB has a sticker for "Solar Ready Pre-Wired", not sure where are the wires, there is no plug on the front of the RV or any where else, neither a plug on the roof, so I don't know where to start.
Please see attached picture showing all the cables located by the battery, I'm assuming that the thick red cable that is going underneath of the RV could be for the 12v interior electrical panel, but what are the second skinner red, blue and yellow cables.

Can I connect the solar panels with the charge controller to the big red and ground?

Did you find your answer? Here's a link to a great solar forum to help you figure out the best way to wire up solar: DIY Solar Power Forum. I've used this a lot with my Class A setup. There are some great diagrams to make sure you're doing it right to include where you need to install protection circuits, etc.

I have a 19erd with a sticker also and it has a "sae" plug on the right-side just above the storage door. All that plug does is connect to the battery. Solar ready,LOL . Just connect your solar controller to the batteries. That battery should be in a box.

I don't have the answer yet, I will be under the trailer this afternoon to chase those extra wires connected to the + to see where it goes and what it powers.

Update, I was able to spend some time today at the RV parking lot, the blue cable is going into the junction box for the 7pin harness and it connects to the black cable of the harness and one of the the break away cable. Fat red is going into the power converter inside of the RV. One of the yellow cables (actually a faded red) is going into the control panel and it controls the slide in/out button. The other yellow that is a faded red is a mystery, it goes into the wall from underneath of the RV and below the window (see pic) but also another 3 cables going into the water pump are sharing the same hole.

Also, I installed the power distribution box and the battery box is ordered from Amazon.
