How To Add A Battery To My Enclosed Trailer

[Ricki Bobby]

I want to be able to run the interior lights I m enclosed trailer when not hooked up to my truck.
I don't need to charge the battery.
What would be the easiest way to go about this?

Find the feed for the lights and hook up to another battery.

My continental enclosed used the charge wire from the truck for the interior lights. I mounted a rv battery on the reach and tied into the charge wire in the front junction box up to the battery so it also charges the battery
