• Recommended 7-Way and 4-Pole Trailer Wiring Harness for 2018 Honda Pilot
  The easiest way to have both a 4-pole and a 7-way trailer connector for your 2018 Honda Pilot would be to begin by installing a 7-way trailer connector, part # 118286 and then use an adapter like # PK12716 when you want to tow a trailer with a 4-pole connector. I've linked to videos for both these products. There's an alternative if you'd rather not mess with an adapter. You can use a T-harness like part # 118384 which would plug inline between the 7-way and the harness provided by the...

• Troubleshooting Stoplight Circuit of 2011 Toyota Tacoma Trailer Wiring Not Functioning
  It does sound like the converter box has shorted out and you would need to replace it with the part # 118496 which is correct fit for your 2011 Toyota Tacoma. If the blinker circuits are still functioning on the trailer wiring but the brake light circuit is dead then that would indicate the circuit board isn't functioning properly and would need replaced.

• How to Install a Trailer Wiring Harness on a 2011 GMC Acadia
  The plug you are referring to in the photo will not be used to install a trailer connector on your 2011 GMC Acadia. The correct way to install a trailer connector on your Acadia would depend on if you have the factory tow package or not. This is an important distinction to make and in order to be sure you know exactly what you have, you will need to obtain your VIN and contact the manufacturer directly. If you do not have the factory tow package then the connections you will need to make...

• No Running Lights on Boat Trailer and Camper Towed by a 2012 Dodge Ram 2500
  The first thing you are going to want to do is use a circuit tester like # PTW2979 if needed and test the connector on your truck to make sure all of the functions are working. If they are not use the owners manual and/or the legend on the power distribution box lid to find the locations of any fuses or relays related to the tow package wiring and replace any that are faulty. If everything checks out on the truck side then that would indicate problems on the trailers. Most likely there...

• How To Find Where the Trailer Running Light Relay Is Located On a Vehicle with Factory Wiring
  I am not sure what vehicle this is in reference to but in order to find out where your trailer running light relay is located you have two options. The first option is to check your copy of the owner's manual to see if it is listed here. If it is not listed in your copy of the owner's manual then you will need to check the underside of the lid for the engine bay fuse box. If you can provide me with the year, make, and model of the tow vehicle I can then look this up for you if listed in...

• Recommended Replacement Trailer Connector for 2019 Chevy Silverado 2500
  To replace the 7-way trailer connector on your 2019 Chevy Silverado 2500 I recommend the Reese Multi-Plug Wiring Harness for Factory Tow Package - 7-Way and 4-Way Flat Trailer Connectors # 74682 for a connection near the hitch. If you want to replace your connector near the license plate, then I recommend the 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket # HM40975. Both of these connect to the factory wiring harness already present in your vehicle. If that harness has been...

• No Trailer Lights After Installing T-One 4-Way Connector on a 2016 Jeep Grand Cherokee
  Wiring harness # 118384 is just a pass-through device. It is designed to work if your 2016 Jeep Grand Cherokee came with the factory-activated towing package. If the Jeep does not have the factory towing package you will need to have a Jeep dealer activate it for you. Otherwise the harness will not work. If your Jeep does have the factory tow package and it is indeed activated and the factory harness had power before you plugged in # 118384 then it is possible that in the process of installing...

• No Power on Tail or Brake Light Pin of Part # 118384
  If you are using the # 118384, and are not getting any signal on the connector for the brake or the tail light, you most likely have blown or missing tow package fuses. These fuses are typically located in a fuse box under the hood, but their location can vary according to the year, make and model of your truck. Your owners manual should have a fuse diagram showing which fuses protect which circuits, as well as the location of the fuses.

• Installed 7-Way and 2012 Jeep Grand Cherokee Dealer Reprogrammed But No Brake Lights/Turn Signals
  If your 2012 Jeep Grand Cherokee did not come with a factory installed 7-Way then if you plug one into the wiring at the back of the Jeep the 7-Way would not function. Like you already did, you would go to the dealer and have them reprogram the computer to get the newly installed 7-Way to function. If everything was installed properly then it should work. If not then they may have made a mistake in the reprogramming process. Or, it could be that there is a fuses or fuses or even relays...

• Troubleshooting Horse Trailer Interior Lights Not Functioning Towed by Ram 3500
  Check the 12 volt accessory circuit fuse of the trailer wiring circuit you have on you Ram. The lights you have on your trailer that aren't working are powered by this circuit and often times it's a blown fuse that causes it to stop working since this circuit is active all the time which makes it easier to short out. Or you can check the pins of your 7-way for corrosion on this circuit and clean as needed as that's the other really common issue that causes problems on this circuit. I...

• Troubleshooting Loss of Power on Jack and Interior Trailer Lights with 2017 Ram
  It sounds like there is likely an issue with the 12V power circuit on your Ram's 7-Way connector, whether your jack and interior lights are powered directly from the 7-Way or via a battery on the trailer that is using the truck's 7-Way 12V power to maintain its charge. What you will want to do first is test the 12V pin on the truck's 7-Way with a circuit tester like # 40376 to see if you are getting power there. The 12V pin should be located at the 1 o'clock position on the 7-Way. If...

• Recommended Wiring for Softside Truck Camper and Boat Trailer On 2014 Ram 1500

• Trailer Wiring Harness Recommendation for 2013 Nissan Xterra
  The Curt Class III hitch you mentioned, part # 13514 is an excellent choice that will work great for you. To provide a 7-way, you'll need the # 118266 wiring harness. In order to provide a functioning 4-pole, you'll need a T harness like part # 118384. If your trailer has electric brakes, you'll need a trailer brake controller. I'd recommend the safer, more predictable braking provided by a proportional controller like the Tekonsha Prodigy, part # 90885. You'll also need the # 3050-P brake...

• Troubleshooting Left Stop/Turn Signals on Trailer Towed by 2007 GMC Acadia
  You have already started the troubleshooting process to find the cause for your trailer's left-side turn and brake lights not working. Since another vehicle has no issue with this trailer this does tend to suggest that the issue is on the Acadia. Since both 4-pole and 7-way trailer wiring setups combined the left stop and turn signals onto one wire, typically a yellow one, what I suggest is that you start a close inspection of this circuit/wire at the trailer connector itself. You can...
