Flat Tow Diode Wiring Kit for 2020 Jeep Cherokee Trailhawk and Parts Needed to Flat Tow


Hi, 2020 Jeep Cherokee Trailhawk. I would like to configure the vehicle as a TOAD. Before purchasing I would like to verify that I am getting the correct wiring kit for my vehicle which has taillights on both rear quarter panels AND the tailgate. I pulled the driver side rear taillight assembly from the rear quarter panel and it had only one small connector. Obviously I would need to access the wire loom where it splits between the 4 taillight assemblies. It may be above the headliner but I don't want to tear apart the new vehicle without guidance. Can e-trailer provide this guidance and recommend the necessary diode kit. Please confirm that the 7 way bumper mounted connector on the Motorhome should be powered by an Auxiliary circuit switched on only when ignition switch is on, NOT directly to the Motorhomes battery.

The correct tail light diode kit for your 2020 Jeep Cherokee Trailhawk is the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267. I have added a link to a video install on a Jeep Cherokee which shows you the process, and the accompanying photo (which is from the video) shows you where the diodes get installed, which is on the same single tail light connector you referenced.

I also wanted to mention that the lights on the hatch (tailgate) of your Cherokee are not going to light up, just the lights that are on the rear panel, as you can see in the other accompanying photo. So you won't be accessing four assemblies, just two. Keep in mind if your motorhome has separate turn and brake signals you will need two additional diodes # RM-792.

Here are all the parts you need in order to flat tow your 2020 Jeep Cherokee Trailhawk, and I have added links to video installs of these parts for you to check out as well.

- Base Plate Kit: Roadmaster Direct-Connect Base Plate Kit # RM-521451-5
- Tow Bar: Roadmaster Sterling All Terrain, Non-Binding Tow Bar # RM-576
- Wiring Kit: Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267
- Supplemental Braking System: Stay-IN-Play DUO Supplemental Braking System # SM99251
- If your motorhome has air brakes: Air Force One Supplemental Braking System for Motor Homes with Air Brakes # SM99243

You may also need a high-low adapter in order to keep your 2020 Jeep Cherokee level, and I've added a link to a help article which shows you how to determine if you need an adapter, as well as a link to our selection of adapters.
