Expert Answers about Jeep JL Wrangler Unlimited


  • Installation of Power Wire of Jensen JWM60A to Replace Jensen AWM970
  • Your Jensen stereo part AWM970 that you have currently has a more traditional power wire setup where one wire carries 12 volts to power the stereo and the other carries a 12 volt signal wire that only is hot when the key of the vehicle is on to tell the stereo to power on. The # JWM60A only has one power wire and that needs to be ran to the hot all the time power source since this is a motorhome application where you'll be using it without the vehicle on. You'll just have to power it off...

  • Where Does the Blue Wire On the Back of the Tekonsha Prodigy P3 Go To On a 2018 Jeep JLU
  • The blue wire on the back of the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 will go directly to the 7-way trailer connector. This wire will need to be at least a 10 gauge like part # 10-1-1. However, there is also going to be wires needed for powering the brake controller and your 7-way so I highly recommend you use the Universal Installation Kit for Trailer Brake Controller part # ETBC7 because it comes with everything you need. Therefore, you don't have to worry about running...

  • Does The ThermaHeat RV Holding Tank Heater Pad Require Special Wiring
  • You'd most likely be fine just using some # 16-1-1 with the standard casing but you could also get some wire with exterior rated jacketing if you wanted to go the extra step. You can also get some wire loom # 7509-10 and run it the length of the wires and use electrical tape to secure it. When installing the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000164 you'll also want to use a switch like # 37212595 to be able to turn it off when not needed to avoid an unwanted...

  • Parts Needed to Install Redarc Tow-Pro Elite Brake Controller in 2018 Jeep JLU Wrangler
  • Since you mentioned your dealer installed wiring on your 2018 Jeep JLU Wrangler, I assume that does mean you have both the 4-Way # 118786 and 7-Way # ETBC7 hooked up. If so, you are ready to go with just a few parts needed to install the Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR. You mentioned you did not have the plug, but it should be underneath the dash to the left of the steering column, taped to another harness near the emergency brake pedal as in the accompanying photo....

  • Wiring SnowBear Personal Snowplow on 2018 Jeep JL Wrangler
  • Your existing SnowBear Personal Snowplow # SB324-081 is also confirmed to fit your new 2018 Jeep JL Wrangler and it will work great. The wiring to the vehicle battery will be the same as it was on your 2013 model Wrangler. I have attached the manufacturer's winch wiring diagram that you can also use for reference. The Curt Front Mount Hitch # C31086 that you had installed on your 2013 Jeep Wrangler will also mount to your 2018 JL Wrangler. For a new set of hardware you can use the Replacement...

  • Can 3rd Brake Light on 2018 Jeep Wrangler be Used When Flat Towing
  • The 3rd brake light on your 2018 Jeep JL Wrangler runs on a separate circuit so while it's possible to have it activated while flat towing the vehicle it's not something that any of the harnesses we have available are designed to work with, including the Roadmaster Diode Kit # RM-15267 that you referenced. If you really want to activate the 3rd brake light you will need to add a converter like # 118158 that will tap into the combined turn/brake circuits on the Roadmaster harness. On the...

  • Can Extension Piece on Thule Roof Cargo Basket # TH859XT-8591XT Be Removed
  • Yes, the extension on theThule Roof Cargo Basket # TH859XT-8591XT can be removed so that you can use the basket in its original length of 49 inches. With the extension added the basket measures 69 inches long. If you think you will use the extension piece at some point on the vehicle then this is definitely the way to go, since it gives you the option of going with either the longer or shorter cargo basket. I have attached a short video demonstration that you can also check out.

  • Roadmaster BrakeMaster System RM-9160 in 2018 Jeep JL Wrangler Unlimited with Diode Kit
  • The Blue Ox 4-diode tow bar wiring kit # BX8848 that you have installed in your JL Unlimited will not cause issues with the brake lights on the Jeep since it will be in Tow Mode when you are flat towing it. This will allow the motorhome to control the lights. In your 2018 Jeep JL Wrangler Unlimited the Roadmaster BrakeMaster System # RM-9160 will install using a Stop Light Switch kit # RM-751000 which provides a separate "brakes on" signal path back to your motorhome. To use this braking...

  • Is the Replacement Lithium Converter PD4045LICSV Capable of Lead Acid Charging
  • I reached out to Progressive Dynamics and found that the PD4045LICSV is only capable of charging lithium batteries. In order to be able to charge both lead acid and lithium, you will need the Replacement Converter Section for Progressive Dynamics 4000 Series RV Power Control Center - 45 Amp # PD4045CSV that you mentioned. This has a built in switch that will let you select lead acid or lithium. I have attached a review video for your reference.

  • Installation of Trailer Hitch on 2018 Jeep Wrangler JL with Additional Bracket at Frame
  • The Draw-Tite Trailer Hitch Receiver - Custom Fit - Class II - 1-1/4" #36424 has been discontinued but was a fit for the standard bumper on a 2018 Jeep Wrangler JL. It will not slip over the bracket you reference so it is not a fit for your specific vehicle due to that bracket. Instead I recommend the Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C13392 which doesn't have the weldnuts attached to the hitch. This will allow you to attach the hitch underneath the bracket...

  • Does Hot Lead on Wiring Harness for 2018 Jeep JL Wrangler Unlimited Have to be Run to Battery
  • Thanks for the purchase and that is a good question, but you must run the hot lead directly to the battery when installing a 4-way, which in your case is the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56407. The reason is this is the only way to ensure your car's wiring is not otherwise affected, and you can run the hot lead from your battery in any manner you see fit. To do this you may need Wire Loom, 10' Long # 7509-10 and Loom Clamp -1/4" # A0250....

  • Installing Redarc Tow-Pro Brake Controller on 2018 Jeep JL Wrangler Unlimited with Tow Package
  • If your 2018 Jeep JL Wrangler Unlimited is equipped with the factory tow package, which should include a 7-Way connector at the rear bumper (you can check to be sure), the only additional components you will need outside of the Redarc Tow-Pro Elite Brake Controller # RED44FR itself is the Tekonsha Plug-In Wiring Adapter # 3073-P and Tow Pro Adapter # 331-TPH-017. The Tekonsha Plug-In Adapter will simply get plugged into the factory port beneath the dash of your Wrangler at one end and...

  • Trailer Hitch Wiring, Hitch and Brake Controller for 2018 Jeep Wrangler JL Unlimited
  • The wiring you need to add a brake controller and tow a trailer with electric brakes with your 2018 Jeep Wrangler JL Unlimited starts with a 4-way, the T-One Vehicle Wiring Harness # 118786, and I've added a link to an install video of this harness on an '18 Wrangler for you.

  • Wheel Chock Recommendation for Use with Off Road Jeep Trailer Parked on Incline

  • Can Diodes for InvisiBrake be Installed on Wiring for Trailer Plug of Towed Vehicle
  • Although it would be easier to install the diodes like part # RM-792 on the trailer connector, for the InvisiBrake # RM-8700 to work properly the diodes need to be installed at the rear of the bulbs. The reason for this is that the 4-Way trailer connector recieves the signal "after" the lights so they wouldn't be effective.
