Parts Needed To Add A Battery To An Enclosed Trailer  

Question:

I have an enclosed trailer with interior lights. The trailer has a 4-flat wiring system and no brakes. My truck has both a 4-flat and 7-round receiver. The lights only work when the trailer is connected to the truck and the truck lights are on. I’d like to add a battery to the trailer so I can have the interior lights on without being hooked to the truck. What parts do I need and how would implement the battery? Thanks in advance!

Expert Reply:

In order to add an auxiliary battery to your enclosed trailer you would need some primary wire to go from the interior lights to the battery part # 12-2-1 (per foot), a 7-way trailer connector to charge the battery part # PK12706, and then some more primary wire to go from the trailer connector to the battery part # 12-1-1.
