Expert Answers about Jeep Liberty


  • Installing Monitor Circuit for InvsiBrake System Through Umbilical Connecting Motorhome and Vehicle
  • The Roadmaster InvisiBrake would be installed per the procedure mentioned on page 14-15 of the installation instructions that I've linked for you. Usually, you'd just use the single wire umbilical included with the kit. You could simply zip tie this extra wire to the umbilical you purchased. If you wish, you could eliminate the umbilical, and simply wire the circuit using an unused circuit in your coiled cord you just purchased. You'd need to cut the plug off the car and the motorhome end...

  • Does Derale Transmission Cooler Install Require Teflon Tape
  • I would not recommend using Teflon tape with Derale transmission cooler installs or with compression fittings like part # D13032. They aren't needed if the fittings are tightened down properly and if for some reason if the tape was to break off and get into the transmission fluid it might negatively affect the transmission.

  • Will Derale Series 7000 Transmission Cooler Help a 2007 Jeep Liberty
  • Yes, transmission coolers work to help your transmission run cooler and extend the life of your transmission and fluid. This cooler will work on your Liberty if there is enough room in front of the radiator or air conditioning condenser to mount the unit. The Derale Tube-Fin Cooler, part # D13101 is 3/4 inch thick by 5-1/8 inches wide and 12-3/4 inches long. You will have to measure the space you have and order accordingly. I have posted a link below to help you select a cooler for your vehicle.

  • Installing 7-Way Trailer Connector on 2009 Jeep Liberty
  • You're on the right track. You'd first need to install a T-1 connector like part # 118554, which will provide a 4-pole connector for the trailer lighting functions. To convert to a 7-way connector, you'd use the # 37185 adapter, which will plug into the 4-pole provided by the 118554 and provide you with both a 4-pole and a 7-way trailer connector. This is the way you'll want to go if your trailer is NOT equipped with electric brakes. However, if your trailer has electric brakes, and you'd...

  • Best Way to Wire 7-Way 12-Volt Circuit and Power Wire for Powered Taillight Converter
  • You can use a single wire to make that run to the vehicle battery. Run the 12-volt circuit from the 7-way, via the 40 amp breaker included in the kit. At the rear of the vehicle, you can tap the power wire from the converter into that 12-volt accessory wire, but be sure to use the inline fuse holder included with the converter. I've linked you to an article and some install videos that you might find helpful.

  • How to Wire the Roadmaster Single Park Light Diode # RM-690
  • Wiring in the parking light diode # RM-690 is easy. All you have to do is locate the wire leading to the parking light bulb. Cut the wire and insert the diode in-line with the wiring. The IN side will be the part of the wire that leads to the front of the vehicle. The OUT side goes to the bulb. Using these diodes prevents back feeding problems when using a supplemental braking system. I included a picture showing how you would wire the diode.

  • Installing Tow-Ready T-One Vehicle Wiring Harness On 2010 Jeep Liberty
  • The T-One Harness, part # 118384 is designed for vehicles that either have a 7-way already installed on the rear of their vehicle or they have the US car connector tucked up behind the rear bumper. It would have a plastic cap on it. Since you said you cannot find the connector on your Liberty it makes me believe there is not one on your vehicle. The 118384 would not work if that is the case. If you do not have the connector or a 7-way on your Liberty you would need part # 118554. This...

  • Where Do Extra Diodes Go When Wiring A Tow And Towed Vehicle With Separate Brake And Turn Signals
  • The other two diodes are needed so you can have separate turn and brake signals. So you will have a diode for each brake light (right and left), a diode for each turn signal (right and left) and a diode for each tail light (right and left). I will send you a link to the wiring diagram of the # RM-154 wiring kit to show where all of the diodes are connected and what color wires go to what function on the tow vehicle. A separate wire for the brake circuit will have to be run on the towed...

  • How To Wire A Towed Vehicle When Both Vehicles Have Separate Stop And Turn Signals
  • The Tow Ready Vehicle To Vehicle Taillight Converter, # 118158, you have referenced will not be needed since you will be staying with a 3-wire system (separate stop and tail lights)on both of your vehicles. The converter is only needed if you had a 2-wire system (combined stop and tail lights) on the towing vehicle and a 3-wire system on the vehicle being towed. I would recommend using a diode system to wire your vehicle because the diodes will prevent feedback from going from the taillights...

  • Brake Controller Installation on 2012 Jeep Liberty w/ Factory 7-Way Trailer Connector
  • Jeep didn't put a brake controller connector under the dash of the 2012 Liberty. To install a brake controller, you will need to a little bit of wiring. The wire Jeep provides is the electric brake output wire that goes back to the 7-Way trailer connector. This wire should be a light green or blue wire that is near the emergency brake pedal or above the kick panel to the left of the emergency brake pedal. It will connect to the blue wire on the brake controller. You will need to wire...

  • Can 4-Way be Added to 2009 Jeep Liberty Which has Tow Bar Wiring
  • Yes, you can absolutely use the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118554 on your 2009 Jeep Liberty that has been wired to be towed behind your motorhome so long as your existing wiring does not also plug into the tail lights like this harness. That should not be an issue though because most tow bar wiring, such as the Roadmaster # RM-154 simply gets spliced into your tail light wiring. I've added links to video installs of Wiring Harness # 118554 on similar...

For this system you need part # TH712400, and part # TH710401.Thule also lists a 150 pound weight capacity with this system on your Jeep. To be able to carry 2 kayaks on the roof may pose a problem due to the room.

  • Wiring Instructions For Tekonsha Brake Controller # TK90160 On 2006 Jeep Liberty
  • The installation of the Tekonsha Primus IQ Trailer Brake Controller, part # TK90160, on your 2006 Jeep Liberty with a factory 7-Way will require hardwiring the wires from the back of the brake controller to the vehicle. The vehicle does not have a brake controller port that a brake controller can plug into. The four wires on the back of the brake controller are wired as follows: The black wire is the 12v power lead and is attached to the positive battery terminal with a 20 amp or 30-amp...

  • In order to install the Derale Series 8000 Plate-Fin Transmission Cooler Kit part # D13503 on your 2011 Jeep Liberty you will first need to identify which of the two transmission fluid hoses that leads into the radiator is for the return. This can be done by taking a quick trip around the block, grabbing each line with your hand, and feeling which is colder as that would be for the return. Once you have found this return line you will remove it from the radiator and route it to the new...

  • Can the Blue Ox Base Plate Safety Cables Have Chains Added to Tow a Jeep Out of a Mud Hole
  • I contacted our representative at Blue Ox and the safety chains included in the Blue Ox base plate kit # BX1131 and the base plate themselves haven't been tested as a recovery point to pull a Jeep out of a mud hole. I wouldn't recommend it and I think your best option is to get tow strap. It's inexpensive and will provide you a peace of mind when the time comes to safely pull a Jeep out of a mud hole. A tow strap I recommend is the Erickson tow strap # EM59700 that has a break strength...
