Expert Answers about Jeep Grand Cherokee L


  • Will Wireless Tow Lights Interfere with the Blue Ox Patriot Braking System
  • No, wireless tow lights like the Custer Wireless LED Tow Bar Light # LIW-LDTL-7B will not interfere with the monitor of the Blue Ox Patriot Radio Frequency, Portable Braking System # BLU37TR.

  • Does Curt Hitch Install Behind Bumper Panel on 2023 Jeep Grand Cherokee L
  • Yes, the Curt Trailer Hitch Receiver # C96NR will sit behind the rear bumper panel on your 2023 Jeep Grand Cherokee L. Like the factory hitch, this will be completely hidden when the panel is in place. If you plan on doing some towing, you will also need the T-One Vehicle Wiring Harness # TK39VR. This plugs into the connection points behind your tail lights. Once installed, you will have a 4-way to power your trailer's signal lights. In order to complete your setup you will also need...

  • Can The Pollak Starter Solenoid Be Installed Exposed to the Elements?
  • Yes, you can absolutely install the Starter Solenoid # PK5231201 exposed to the elements. This is designed to be installed inside your vehicle's engine compartment which is not exactly sheltered from the elements, so you shouldn't have any issues. To install this, you'll just want to run a wire from the positive terminal on your vehicle's battery to the left post on the solenoid, and then from the right side of the solenoid, you'll run a wire to whatever accessory you're trying to power.

  • Will Curt Echo Wireless Controller Still Work if Phone is Disconnected
  • Great questions! The Curt Echo Wireless Trailer Brake Controller # C51180 will operate using the settings that you chose in the iPhone app regardless of whether you have the app pulled up or not so you can jump from one app to the next or even turn your phone off without it affecting the braking performance of your trailer. I do recommend leaving your phone alone while driving though. I like to recommend the Manual Override Button # C83HR for the Echo Wireless controller because it means...

  • How Many Diodes are In Tow Bar Lighting Kit for 2023 Jeep Grand Cherokee L
  • I am not sure exactly what lighting kit you ordered for your 2023 Jeep Grand Cherokee L but I would assume you most likely did not install a 6 diode kit which is not required at all. Most likely you have a 4 diode kit like the part # RM-15267 which is a very popular option. There isn't a fuse removal required for your vehicle either. I attached an install video for the lighting kit on a similar 2022 Grand Cherokee L for you to check out as well.

  • How To Install The Universal Installation Kit # ETBC7 On A 2021 Jeep Grand Cherokee L
  • Before installing the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires # ETBC7 you will need to have a 4-pole wiring harness already installed. If you do not then I recommend the Curt Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C27BR. This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light...

  • Recommended Hitch And Wiring For A 2021 Grand Cherokee L Hitch
  • As the maximum towing capacity for a 2021 Jeep Grand Cherokee L is 7,200 pounds and the maximum tongue weight capacity is 720 pounds (equipped with all-wheel drive and the 5.7L V8), either hitch will be limited by the capacity of your vehicle. With that said, the American made Curt # C97JR is the hitch I tend to recommend, though it does not come with the wiring bracket the Draw-Tite # DT42GR has. Curt doesn't use this bracket on any of their hitches, unfortunately, but this does not mean...

  • What 7-Way Wiring Needs to be Ran for Bluetooth Brake Controller on a 2021 Jeep Grand Cherokee L
  • The Universal Installation Kit # ETBC7 comes with all of the wiring and connections needed for a traditional in-cab brake controller, but since it sounds like you'll be using one of the Curt Echo brake controllers (linked below) you won't need to run the blue wire - you just need to make the 12V power connection for the brake controller to work properly. We actually have a wiring kit built for Bluetooth brake controllers found as the Upgrade Kit # ETBC7L. Here is a list of the Curt Echo...

  • How to Identify the Cold Side of the Brake Light Relay On a 2022 Jeep Grand Cherokee
  • Roadmaster has identified the wire that you'd need to cut into on many YMM vehicles, however your 2022 Jeep Grand Cherokee Summit Reserve is not one of those vehicles. So, you'll have to do it the old fashion way. You'll need to locate your Jeep's brake light switch and, with a volt meter # PTW2992, find the ‘cold’ side of the brake light switch wire which the volt meter will not register voltage unless the brakes are applied; and when the brakes are applied the volt meter will register...

  • How Long Does it Take to Install a Trailer Hitch on a 2023 Jeep Grand Cherokee L
  • The trailer hitch installation times on a 2023 Jeep Grand Cherokee L will vary by hitch type and experience level. The Curt Trailer Hitch Receiver part # C97JR is what I recommend as it offers a bolt-on fit with no drilling required. It's not hard to install but will take a bit of time since the rear bumper has to come off. That said, not to worry as we have a video which shows you how to do this from start to finish and I have attached that for you below. The installation time we estimate...

  • Is There An Easy To Install Hitch For A 2021 Jeep Grand Cherokee L
  • The hitches we have available for your 2021 Jeep Grand Cherokee L, like the Curt # C97JR, are going to be a bit more involved than others. This is due to the lack of room on the underside of the frame and where the exhaust and spare tire sit. However, once it is installed it will be completely hidden when not in use. So that's a plus. This is also a very capable hitch. The maximum towing capacity of a Grand Cherokee L looks to be 7,200 pounds (check your owner's manual to confirm the capacity...
