Question:

Thank you. I am looking into purchasing a Blue Ox Patriot Braking System. I have a 2020 Jeep Cherokee Trail Hawk 4X4 Red Tow Hooks on Front. What wiring harnesss would you recommend to prevent battery drain while flat towing? I recently ordered the base plate from you all, so just trying to get the parts together for install. Any help is appreciated.

We do have what you're looking for, but the charge line and tow bar wiring will be two (potentially 3) different parts. For your tow bar wiring I recommend using the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 since the diode kit allows you to use your Jeep Cherokee's tail lights and wiring system while preventing feedback from your RV.

Once you've installed that, you'll need the Roadmaster Battery Charge Line Kit # RM-156-25. This kit allows you to connect your Jeep's battery to the 6-Way or 7-Way plug at the front of the vehicle so that up to 15 amps from the RV's battery can be used to maintain its charge while being towed. If no charge line is present in your RV, you will also need to add the Motor Home Charge Line Kit # RM-156-75 to provide the battery charge directly to the vehicle installed charge line.

I've attached some installation videos of these parts for you to have a look at, but these will allow you to keep your 2020 Jeep Cherokee battery charged while using the Blue Ox Patriot # BLU37TR during flat towing.
