Wiring Question

I have a 2018 Jayco 265RLS

Connected to the battery on the tongue is a Black Wire (10g) which is connected to the chassis, as well as the Neg side of the Dist panel inside the camper. There are two Red Wires (10g and 16g) connected to the positive side of battery. The 10g is connected to an inline fuse, then onto the Dist panel inside the camper. The 16g seems to run into the frame of the camper (with the rest of the bundle), but I can't locate where it goes. Anyone have any idea what this wire is for? I've requested a wiring schematic from Jayco, but they don't seem to be in a rush to send it along.

Battery monitor?

Do you have a battery monitor on your rig? Other than that - possibly the CO/Gas monitor. Two SWAG's

That second red wire probably goes to your 120V to 12V converter to charge your battery.

It might also go to your trailer's break away switch.
