Question:

Question: Im towing a 2020 Jeep JL installed the Invisibrake on my car . Everything was fine when I was driving short distance, but now my battery is going dead after long distance, 800-1000 miles of towing the vehicle. I have to jump start the car to start it . Is it possible to use the current from the Motorhome battery for the invisibrake system? Do I need an extra charging wire to the battery with a 20 amp fuse or how can I charge it through my plug wiring. 2021 Thore Outlaw - 2020 Jeep Wrangler

A charge line is definitely what you need to keep your Wrangler's battery from dying on long trips. I recommend the Roadmaster Battery Charge Line Kit for Towed Vehicles item # RM-156-25. This charge line connects to the 6-way or 7-way plug on your Jeep.

If your Thor Outlaw's 7-way connector does not have a functioning charging circuit you will also need the Roadmaster Battery Charge Line Kit for Motorhomes item # RM-156-75.

I have linked a couple of installation videos below so you can see how to set these parts up.
