• Flat Towing Lights Recommendation for 2016 Jeep Wrangler Since Magnetic Cant be Used
  The removable lighting solution to use on a 2016 Wrangler is the part # RM-2120 as this will install between the tailgate. The magnetic lights aren't a fit for your vehicle realistically since there isn't a place to attach them. A customer of ours used this kit on his 2015 Wrangler and here is how he said he was able to install the kit. I open the tailgate to first hang the passenger side light then close the tailgate which serves to lock the passenger light in place and allow enough of...

• Is the Brake Light Relay Needed when Installing Invisi-Brake on a 2012 Jeep Wrangler
  There are a lot of caveats for when the brake light relay # RM-88400 is needed or not needed. But we have taken the guess work out for you. The relay is required on the 2012 Jeep Wranglers. If you turn the key to the position it is supposed to be in for flat towing (consult the vehicle owner's manual) that is the position of the key you would use to test whether or not the brake lights come on.

  In order to activate the tail lights on a 2020 Jeep Wrangler Unlimited from the motorhome you will need a flat-tow wiring harness, the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit part # RM-15267 is our best and most popular option for this.

  From what I could find out, the Mopar Recreational Flat Tow Wiring Kit will not be needed for a 2020 or 2021 Jeep Cherokee Trailhawk. This was only a requirement on a 2014 to 2018 as the issue this was designed to combat has since been rectified.

• What Circuit of the Roadmaster RM-155 Does the Brown Wire Run to
  The issue is the way you wired up the brown wire. This needs to run to the running light circuit of your vehicle. This is the circuit that activates the dimmer illumination of the trailer lights you have on your vehicle. It would not run to both the brake and turn signal circuit like you mentioned. I attached a link to an install video for the # RM-155 being installed on a similar Liberty as yours.

  Wire colors are not a reliable way to determine what you need to connect, so in order to determine the specific problem you'll need to use a circuit tester such as # PTW2993 to test the connector and hook up your lights according to the functions.

Check the wiring going into your harness from your taillights to see if those wires are carrying the correct signals, if not then the...

• Tow Bar Wiring for Use on 2017 Jeep Wrangler that Has Ready Brake Supplemental System
  The Ready Brake you have is supplemental brake system for flat towing a vehicle and the Hopkins kit part # 42615 is wiring for towing a trailer.

This won't interfere with the operation of the Ready Brake and will activate the taillights as needed. I attached an install video for this kit on a similar...

• Troubleshooting Brake Lights that Turn off when Brakes Applied
  It sounds like you have a ground problem on the trailer. I'd start by checking the ground wire at the trailer coupler and making sure it is connected to a solid clean paint free spot on the coupler or frame. Then I would check the tail light assemblies. Tail lights are usually grounded through their connection to the trailer frame. If you have a plastic license plate bracket on the left side this could be the culprit. You should also check the brackets that hold the lights. If they are...

  What you describe is a ground problem with the trailer wiring. Starting at the rear of the vehicle, confirm that the ground connection on the Plug and Tow Harness is securely fastened to bare metal.

Next, examine the point on the trailer where the trailer connector ground wire attaches. This can usually be found on the trailer tongue. Make sure the wire is in...

  If you are referring to the Mopar harness that fixes the steering stability issue, then it was resolved by Jeep starting with the 2018 models so you won't require it.

• Electrical Connection from Motor Home to a Jeep Wrangler for Tail Lights when Flat Towing
  If you already have the diodes installed, all you have to do is it connect the motor home to the Jeep Wrangler. The diode kit probably came with a 4-Way flat trailer connector that should be at the front of the vehicle. In a perfect world, the motor home would have a 4-Way flat receptacle. If that is the case, just plug then into each other. If the motor home or the diode kit had a different type of connector, you will need an adapter or you may have to hardwire in the correct connector...

  Even though the plug was found on the driver's side it does sound like your mechanic found the correct plug for the Hopkins # 42615 on your 2003 Jeep TJ. If the lights on your Jeep are working normally then that leads me to believe that the wiring harness is messed up somewhere. Try piercing the wiring harness at different points to see if the signal is lost somewhere. Typically this would be a ground issue but if your ground is secure and connected to a clean, bare-metal surface then...
