Question:
Ok. Just making sure. I didn't know if having the trailer plugged in with the vehicle off would run all the juice from the vehicle battery to the trailer battery while being off or if it would need something to tell it to only give the trailer battery power while the vehicle is on. So that it wouldn't run my car battery down.

We can set you up with everything you need, but we do not have a kit for adding a charge line to your 7-way.
All you need is wire and a circuit breaker. You'd need a length of 10 gauge wire like part # 10-1-1 (sold by the foot) to run from the 1:00 pin of your 7-way to the positive post of the battery through a breaker like part # 9510 and you'd be set.
