Trailer Battery Feed Question

[Appleboy84]

2013 Chevy Silverado LT, All Star Edition (Has Trailering Package), 5.3L, completely stock. I recently bought a new camper. This camper has a battery unlike my last one. It seems in the owners manual, as well as other places online, I read that the auxiliary battery wiring is not hooked up to charge the battery on my camper. Am I understanding this correctly? If so, what is the process of wiring up the truck so I can charge the battery on my camper while towing?

There are two set of wires you can connect.  One is between the underhood fuse box and the fender and the other is in front of the brake booster, under the master cylinder, coiled in tape.

 

The wires along the fender are for an aftermarket trailer brake controller.  If you have JL-1, you won't need to do this (instruction on A-82).
