Adding Interior Lights to Trailer and Keep Battery Charged
Question:
Could you give a a step by step on the wire hookup? . I’m assuming that I will the wires about 12 inches back from the plug that goes to the back of my truck and hook up one wire to each prong on the junction box. So at this point I will have 2 wires on each prong one from the trailer to the junction box and one from the Jbox to the plug that goes to the truck. Ok so if that’s right so far now I would have to run some wire from the Knox to the new battery then to the switch then to the light then back to the battery. Could you just gone me the hook up instructions thanks

The best way to get interior lights in your trailer is to have a dedicated 12 volt battery, and battery box like # 329-HM318BKS mounted to the trailer. This gives you the power needed while you're not hooked to your truck.
For lights I recommend LEDs because they require much less power, and last longer than incandescent bulbs. Which lights I recommend depends on how many you want to add and the way you want to mount them. You'll need wire # 12-1-1 and ring terminals # 44-5310A for each light. For a switch you can use Pollak Heavy-Duty Toggle Switch # PK34571.
The new battery can be hooked into the 7 way on your trailer using a junction box # 38656, and then when you're hooked up it will provide a maintenance charge. This however will not completely charge a dead battery. If you plan on being unhooked for an extended period, or your trailer battery is depleted I recommend using a battery charger like CTEK MULTI US 7002 12-Volt Universal Battery Charger # CTEK56353.
I linked the parts mentioned above, a few videos as well as our selection of LED interior trailer lights for you to check out.
