Expert Answers about Jeep Wrangler


  • Installing Diodes To Prevent Backfeeding From Towed 2012 Jeep Wrangler Sport To Motorhome
  • You are getting backfeed from the Jeep through the wiring harness back to the motorhome. I spoke to my contact at TrailerMate and they told me the diodes included with this system are not designed to prevent backfeed. We have a solution that will take care of that. You will need to install diodes like part # RM-690 on the yellow left turn wire at the back of the connector on the harness that plugs into the left tail light assembly, and also on the green right turn wire at the back of...

  • Troubleshooting Running Lights not Working With Roadmaster Diode Flexo-Coil Wiring Kit
  • What we have found when there is an issue with running lights but not other lights when installing the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 is that the problem is almost always due to an issue with the diodes. So if the wires are not properly routed with the diodes, or there is an issue where a wire was somehow crimped or damaged then the running lights would not work. You need to create a jumper wire and attach the diodes that way, which may have been the...

  • Adjusting Settings for New Install of Blue Ox Patriot Portable Braking System
  • You can adjust the Blue Ox Patriot # BLU37TR using the sensitivity adjustments in the setup screen. The large number on the display represents the force setting. I suggest you hook the Jeep up to the motor home and test braking with it in a open area away from other vehicles. Test for max force by setting to maximum amount and verifying it engages. If it does, back off the setting until you feel engage with a reasonable response. Let us know if it does not engage and we will troubleshoot...

  • How To Connect A 7-Pole Diode Wiring Cable To A 4-Pole Connector On An RV
  • Since you already have a 4-pole wiring harness on your RV you would just need to install a 4-pole to 7-pole Adapter # 37185 to get a 7-way connection at the end of your motorhome and allow you to hook up your straight cable from your Roadmaster 4-Diode Universal Wiring Kit # RM-152-98146-7. To install this kit you'll need to make the following connections: The 4-pole connector to the one already on your RV. The blue wire to the brake controller. The purple wire to the reverse light...

  • Troubleshooting Trailer Wiring Harness Blowing Fuses on a 2006 Jeep Wrangler
  • Both of the wiring harnesses we have available for the 2006 Jeep Wrangler, will work on your Jeep. The difference is that one is manufactured by Tow Ready, # 118409, and the other is manufactured by Hopkins manufacturing, # 32625, and that different connection points are used by the different manufacturers. It sounds like you might have one of several problems. First, check the connectors in your existing trailer wiring harness and on the Jeep to make sure that none of the pins are bent,...

  • Troubleshooting No 12V Power on 2017 Unity RV 7-Way
  • If you have a factory 7-way on your 2017 Unity RV there will be a fuse assuming the 12V power is hooked up. You can check your owner's manual for the fuse location or look on the fuse box lids to identify it. Looking at fuse box diagrams online there are more than 2 locations, but I didn't see anything specifically for towing. There would not be a fuse in the 7-way connector. If the 12V power is not connected you could add a charge line # RM-156-75 to solve the power problem. I'm not...

  • Troubleshooting Turn Signal Not Working on Hopkins Tow Bar Wiring Kit for Jeep Wrangler
  • It's possible the converter box had an internal problem which caused it to stop working, but to test this you need to reinstall the part # HM56200. Use a circuit test like part # PTW2993 to test the voltage going into the box and coming out. If the voltage on the left turn signal is present on the input side when the turn signal is on but not the output side the box is at fault. If there's no voltage on the input then the issue is either the wiring or the connector not making good connection. You...

  • Fix For Curt Echo Wireless Brake Controller Locking Up Trailer Brakes At Low Speeds
  • We have actually run into this issue quite a few times in the past, and there is a simple fix. The reason the Curt Echo Wireless # C51180 locks up the brakes on your camper only at low speeds is due to it being paired incorrectly, usually plugging in the trailer to the Echo before plugging the Echo into the 7-way connector. You will need to delete the Curt Echo app and start the pairing process over again. Plug the Curt Echo into the 7-way connector on your 2013 Jeep Wrangler without...

  • Troubleshooting Roadmaster EvenBrake That Doesn't Pump Brake Pedal During Test
  • When you test the Roadmaster EvenBrake # RM-9400 it should conclude the test by pumping the brake pedal 3 times. It sounds like there might be an issue here with the Roadmaster EvenBrake # RM-9400 and the new vehicle might not have the Stop Light Switch # RM-751452 installed on it, which is required. If you've got the Stop Light Switch installed in the new vehicle and this malfunction is still occurring, let me know and I can give you a few other things to look at to get you back on the road.

  • Troubleshooting Trailer 7-Way Detaching From Curt Echo Wireless Brake Controller
  • I'm sorry to hear you have had trouble with your Curt Echo # C51180. Although there have been some reports of the Echo falling out of the vehicle when not secured with the strap, we have not received any about the trailer wiring falling out of the Echo itself. When plugging your trailer's 7-way into the Echo make sure it is fully seated for a secure connection. Also, make sure that the tab underneath the cap is in place behind the tab on the top of your 7-way connection. This will keep...

  • Installation Troubleshooting of Roadmaster Crossbar-Style Base Plate Kit
  • The Roadmaster Crossbar-Style Base Plate Kit, # RM-521448-4, is a confirmed fit for the 2013 Jeep Wrangler. And the Roadmaster Sterling All Terrain, Non-Binding Tow Bar, # RM-576 is a match to those base plates. Manufacturing variances occasionally cause difficulties with installation. Depending on if your vehicle has a hole on the outside of the frame or not, you may have to drill one. I have attached a video of these base plates being installed on a 2013 Jeep Wrangler. Please checkout...

  • Can Prodigy P3 Brake Controller be Tested without Trailer Being Connected
  • If the Prodigy P3 brake controller # 90195 has any issues when not connected to a trailer it will display them on the screen of the controller. If no error codes are present it's ready to be used without any issue. It does take a trailer to be connected for the complete system to be checked and there's no way to do that without a trailer connected.

  • Brake Lights Not Working After Install of RM-88400
  • If you have a flat tow wiring kit with diodes, then you need the Roadmaster # RM-88400 Brake Light Relay Kit. It is normal behavior for those lights not to work when the wiring kit is active. We want the towing vehicle (through the wiring kit) to control those lights.

  • What Can I Do To Charge The Battery Of My 2020 Jeep Wrangler While It Is Being Flat Towed
  • Yes, there is a charge line kit that will eliminate this issue for you. You will need the following items: Roadmaster Battery Charge Line Kit for Motorhomes, part # RM-156-75 Roadmaster Battery Charge Line Kit for Towed Vehicles, part # RM-156-25. The motorhome charge kit will connect that battery to your 6-way connector on the rear of your motorhome. The battery charge line kit for towed vehicles will connect your 2020 Jeep Wrangler Rubicon's battery to its 6-way connector. Once connected,...

  • Troubleshooting 2014 Jeep Wrangler Brakes Pulsing With Motorhome Turn Signals
  • From what you described it sounds like you need to install the Roadmaster Brake-Lite Relay Kit # RM-88400. If your towed vehicle is the 2014 Jeep Wrangler that you input for your vehicle information then this makes sense. Typically we recommend disconnecting the battery when flat towing this vehicle. If you were to disconnect the battery then your SMI Stay-IN-Play DUO # SM99251 wouldn't cause the brakes to pulse when your blinker is used on your motorhome. When I spoke with my contact...

  • Troubleshooting Yakima Sparetime Bike Rack with Frozen Locking Knob
  • Usually the locking knobs on racks will also require you to push (or pull) on them while turning to get them to engage with the internal release mechanism that loosens the rack. If the lock mechanism rusted/corroded while in the locked position it may not engage properly even if you turn the key to the "unlocked" position. Applying a spray lubricant like WD40 or PB Blaster as you did is a good effort; sometimes these products can take a while to work. Often multiple applications are needed,...

  • Troubleshooting Kwikee Step on 2013 Jayco Greyhawk that Clicks
  • Sounds like the motor is on it's way out if it's clicking. Similar to how a car starter will start clicking when it has failed and draws too much amperage to operate. Since the trailer is newer (2013 Jayco Greyhawk) you would most likely need the newer style of Kwikee motor part # LC379147 which fits Kwikee steps manufactured after 2005.

  • Troubleshooting Trailer Lights Not Working When Tow Vehicle Headlights Turn On
  • Typically when turning on one of the light functions causes the other lights to cut out, it signals an issue with the ground connection on the trailer; the # ST6RB and # ST7RB lights both ground independently with their mounting hardware but there should be a ground wire on the trailer. I would start by checking the ground connection there and also cleaning off the trailer connectors to make sure there isn't any dirt or debris that's causing an issue. The next thing I would check out...

  • Troubleshooting 1998 Wrangler Lights Not Working With Roadmaster Diode Wiring Kit
  • If your 1998 Jeep Wrangler's lights are not working with the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 and you do not have a proper ground then the lights are not going to work properly. You are going to need to attach the ground wire with the ring terminal and self-tapping screw directly to your Jeep's frame in order for all of the lighting functions to work properly. Also keep in mind if you are using a supplemental braking system such as the SMI Stay-IN-Play...

  • Even Brake Supplemental Braking System Interferes with Home Security System
  • The Even Brake, # RM-9400, sends a wireless signal to the receiver in the motorhome hand held unit and that signal can interfere with other signals. It sounds like the unit is sending a signal either looking for the hand held unit or something similar. You will want to unplug the transmitter from the power source and Even Brake. With no power the unit should not be able to send a signal.
