  • Can Curt Tow Bar Lighting Kit for 2023 Jeep Gladiator Install with Trailer Wiring
  • Hey Miles, so the Curt tow bar lighting kit part # C96JR that you referenced installs by plugging inline with the taillight connectors of the vehicle so it's not going to interfere with any trailer wiring.

  • Where Does Hopkins Tow Bar Lighting Kit Install on 2004 Jeep Grand Cherokee
  • Hey Andrew, the Hopkins tow bar lighting kit part # HM11142565 that you referenced is a fit for your 2004 Jeep Grand Cherokee but it doesn't install using the connector you mentioned finding. It actually installs by plugging inline with the trailer wiring connector that is found under the vehicle which you can see more about in the attached install instructions link on this page.

  • Recommended Hitch for a 2018 Mercedes GLE 350
  • Curt doesn't make hitches with detachable receivers. The only one they offer that fits your 2018 GLE 350 that does not require trimming is their item # C13294 you were looking at. The Curt Hitch item # C13294 is custom fit and bolts to your Mercedes with included hardware. It is a class III hitch with a 2" receiver. It has a 7,500 lbs towing capacity and a 750 lbs maximum tongue weight. I really like the Curt item # C13294 because it installs behind your rear bumper cover leaving only...

  • Troubleshooting Lights Not Working on 2018 Jeep Wrangler After Diode Installation
  • Based on the fact you're adding the InvisiBrake # RM-8700, I believe you have one of the Curt tow bar wiring harnesses and you aren't actually referring to a trailer wiring harness or trailer lights. More than likely the problem is the diode installation. Double check the diodes and make sure the connections are correct. This is the only thing I know of that would cause the lights to stop working. It wouldn't hurt to double check the rest of the installation just to be sure.

  • How To Install The Putco Blade LED Tailgate Light Bar # P22KR
  • Hi Robert, To install your Putco Blade LED Tailgate Light Bar # P22KR you'll need to just remove the tail lights so that you can get access to the back wiring in the back of them. The plug-and-play connectors on the wire harness with have a male and female connector so that you can connect to factory wiring connector with the female plug and to the tail light with the male plug. This method allows you to install the light bar without having to splice into the wiring.

  • Do AC and DC Grounds Need to Have Their Own Connections
  • Thanks for reaching out, Peter! The Progressive Dynamics 4100 Series RV Converter w/ Charge Wizard and AC/DC Distribution Panel # PD4135K does have separate grounds for the AC and DC power sections. If you check out the linked installation video starting at the 20 minute mark you'll see how we wired in the power center. One of the bus bars is used for the AC ground and the other bus bar is used for the AC neutral and the DC ground.

  • Can I Use the Curt 58963 Tow Harness and the Curt C56406 4-Way Connector on a 2020 Jeep Cherokee?
  • Yes, they will both work with your 2020 Jeep Cherokee so long as you do not have the tow package. The Curt dinghy tow harness 58963 and the Curt T-Connector Vehicle Wiring Harness item # C56406 connect in line to your factory wiring harness. As far as having enough room there's plenty you'll just have to push the wires down below the lights. I have linked an installation video below that'll help you get the 4-Way set up. Please note that you can not use the 4-way when you're flat towing...

  • Installation of Tow Kit Wiring Harness for 2020 Porsche Macan
  • Since you said the tow kit I'm assuming you are referring to the Towing Kit w/ Ball Mount and Trailer Wiring for Stealth Hitches # SH79FR that comes with the # SH84FRT. We don't have an installation video for this one but the instructions can be found below and on the full product page for the # SH84FR. It looks like the instruction link from the # SH84FRT is broken right now so it would be best to get it off of the regular hitches product page. Installation of the wiring kit begins on page 9.

  • Converting From A 3-Wire Tow Vehicle To A 2-Wire Trailer Lighting System
  • Hey Frank, It sounds like you have a 3-wire system on the tow vehicle and you're connecting to a 2-wire system trailer so you'd just need a converter like the Curt # C56196 to make the your lights function properly. If you can give me the year/make/model of the tow vehicle I can see if there's a wire harness with a converter already built into it to make installation easier.

  • Trailer Wiring for 2020 Lexus RX350 That Doesn't have OEM Tow Package
  • Hey Shane, for your 2020 Lexus RX 350 that didn't have a factory hitch the trailer wiring that you honestly should have gone with is the part # C56217 which is for the versions of the vehicle that don't have the tow package. While your vehicle has the connector it's not active which is why it's not working as-is. Maybe Lexus dealer could activate the wiring harness but we don't have any info on that.

  • 4-Way Wiring for 2017 Chevrolet Traverse Without Tow Package
  • Even though you don't have the tow package you can use the T-One Vehicle Wiring Harness for Factory Tow Package # 118270. This will plug into your factory connector at the rear of your 2017 Traverse. It also includes all of the necessary fuses and relays to activate the tow package so it doesn't matter that your vehicle didn't come with it. I have attached an installation video below for your reference.

  • Can The Redarc Tow-Pro Elite Replace A Kelsey Energize Brake Controller In A 1996 Chevy K2500
  • Hello Michael. The Kelsey Energize brake controller will use the same 4 wire connection at the Redarc Tow-Pro Elite # RED44FR. So, it will be a simple matter of disconnecting the old controller and wiring in the new controller with the 4 wires that should be color coded (red to red, black to black ect...).

  • Installing Brake Controller on 2020 GMC Canyon With Tow Package
  • Hi Harold, When installing a brake controller like the Prodigy P3 # 90195 or Redarc Tow-Pro Elite # RED44FR on your 2020 GMC Canyon with the tow package, all you need to do is connect the wiring that comes with those controllers to the wires already run under your dash. I did some searching and found that on page 211 of the Canyon owner's manual it says a four-wire harness is secured behind the left side kick panel (which is the driver's side), and here are the wires in your truck (though...

  • Can Factory 4-Way/7-Way Be Used For Flat Towing 2023 Jeep Cherokee Trailhawk
  • The Roadmaster 4-Diode Universal Wiring Kit # RM-154 needs to be installed on your 2023 Jeep Cherokee Trailhawk for flat towing unless you have ParkSense proximity sensors. If you have ParkSense you need the # RM47ZR instead. The 4-way and 7-way on the rear of your Cherokee are for towing a trailer so they have nothing to do with flat towing and will not work for this application.

  • Recommended Hitch and Wiring for a 2020 Chrysler Pacifica
  • For your 2020 Chrysler Pacifica, I recommend the Curt Hitch item # C65CR. This hitch is custom fit and bolts to your Pacifica with included hardware. I really like this hitch because it tucks up extremely well and the 2" receiver is all you see once it is installed. For wiring you will want the Curt T-Connector Vehicle Wiring Harness item # C56322. This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind your tail lights. It will provide you with a...

  • How To Tell If a 2014 Chevrolet Silverado 1500 Has The Tow Package Wiring For a 7-Way
  • All the 2014 Chevrolet Silverado's should have the factory wiring for a tow package. The 7- and 4-Pole Trailer Connector Socket # HM40975 is the most commonly used part as it will fit right into the factory cutout in the rear bumper and gives you both a 4-flat and 7-way connector like the factory option. I have included an installation video near the bottom of the page so you can see where the factory wiring connector is and how easy it is to install.
