Wiring Kit for the Nighthawk All Terrain Tow Bar to Flat Tow a 2018 Jeep Jk Wrangler Unlimited


Which is the best wiring kit to go with this tow bar since it already has the 6 pin plug and 6 to 7 pin cable? And is it compatible with the roadmaster d ring mounts? I have 2018 4door jk unlimited that im setting up to flat tow.

To complete the wiring kit included for your 2018 Jeep JK Wrangler Unlimited when using the Roadmaster Nighthawk All Terrain # RM-676 tow bar I recommend going with the All Terrain Towing Combo Kit # RM-9284-2. This includes the wiring and diodes needed to complete the wiring as well as a cover and locks for your Nighthawk All Terrain, silicone rv lube, and a storage bag for keeping all of your loose flat towing components in one place when they are in storage.

If you would rather just go with the wiring then you would need part # RM-152 along with the mounting bracket # RM-910030-5. I have attached an installation video for this wiring on a 2017 Jeep Wrangler Unlimited that you can follow if you plan on doing the install yourself.

The Nighthawk All Terrain is compatible with both the 1" D-Ring Adapters # RM-035-1 and the 3/4" D-Ring Adapters # RM-035.

To complete your flat towing setup you also need a supplemental braking system. I recommend using an SMI system that stays installed on your JK whether you are flat towing it or not because it provides you with a proportional braking system that is extremely easy to get ready for flat towing after the initial installation. If your motorhome has air brakes then you want to go with the Air Force One # SM99243 but if your motorhome has hydraulic brakes the Stay-IN-Play DUO # SM99251 is the way to go. Attached are sample installation videos for each system so you can see how they work.

Most flat towing setups also require a high-low adapter for the tow bar to remain level while towing. I have linked our selection of adapters for you to check out as well as an article that will help you determine which is the best one for your application.

Please be sure to reference your owner's manual as well for any specific instructions when it comes to flat towing your 2018 JK.
