Question:

Hi I just bought a 8.5 by 20’ enclosed trailer. They did not put in lighting in it. Which is weird imo but it is what it is. How would I go about adding interior lights with a switch to my trailer? I am pulling it with my 2017 GMC Sierra and it hooks up with a 7 pin connector. Thanks so much for your help

Helpful Expert Reply:

The best way to power interior lights in your enclosed trailer is with an independent 12 volt battery mounted on the trailer.

To do this, mount the battery with Battery Box # TLA7708R and use junction box # 38656 to tap into your 7-way so the battery gets a maintenance charge when you are hooked up to the 7-way. Hooking up the junction box will require ring terminals # 44-5310A, and wire # 12-1-1 to run to each light, and you can use rocker switch # PK34308 to turn them on and off.

Your 7-way will provide a maintenance charge, but in order to fully charge the battery when it is depleted you will need a standalone battery charger, the CTEK MULTI US 7002 12-Volt Universal Battery Charger # CTEK56353.
