Expert Answers about Jeep Tow Bar Wiring

• Troubleshooting a 2020 Ford F-350 That Does Not Have Working Turn Signals When Using a Lightbar
• Hey John, so I would try and see if you can narrow down the issue by removing the light bar and connecting the truck and towed vehicle together and see if the problem continues. If it does then you know the issue is most likely with your connector or your wiring on either the towed vehicle or the truck. If it doesn't, and everything works then you know the issue is with the light bar.

• Blue Ox Tow Bar and Base Plate Kit that Fits 2024 Jeep Wagoneer
• Hey Wayne, so the Blue Ox Base Plate kit part # BLU46CR is a confirmed fit for your 2024 Jeep Wagoneer and while the bracket width is on the wider side it has been tested and works fine with Blue Ox tow bars. We do have the Blue Ox Avail Tow Bar part # BX7420 which does have a lot longer arms which might help you feel better about the bracket width. The arms of this are 42-1/4 inches long. There is a death wobble issue potentially with your vehicle and for that you might need the MOPAR...

• Can the Demco LED Light Bar Be Connected to a Splitter
• Hey Steve, so in regards to your first question I don't see anything wrong with using a splitter and an extension cord with the Demco LED Light Bar for Towed Vehicles w/ Wireless Transmitter # DM36MV as long as it's getting 12V, and your cords are protected, it doesn't matter. For your second question, there is not really a way to tell but since your Jeep does not have to have it's battery disconnected to flat tow, you shouldn't end up with a dead battery. If it turns out you need to...

• Troubleshooting Trailer Wiring That Activates The Hazards When Using The Right Turn Signal
• Hey Justin, When you say it's triggering the hazards what exactly do you mean? Is it flashing the smaller clearance lights on the trailer? Is it just on the right side or the whole trailer? Most likely the converter box for the trailer wiring harness on your Highlander is malfunctioning and sending the wrong signal back to the trailer. You can't do much to fix this unfortunately besides replacement if this is the case. If you have the factory towing package you can swap out the wiring...

• Best Way To Test Trailer Side 7-Way Without A 7-Way On Tow Vehicle
• Hello Dylan. Without having a vehicle to connect to, the only way to properly test your trailers 7-way is to use a tester like the Tekonsha # 8010 or the Hopkins Tow Doctor # HM50928. These testers provide a power source and will allow you to test all of the functions easily by yourself. These testers are expensive though, so if it were me. I would go ahead and put that money towards installing a 7-way on the vehicle so you can test it that way. If you can let me know the year, make and...

• Troubleshooting A 2017 Ram 2500 That's Sending Constant Power To The Trailer Running Light Circuit
• Hey Karl, The trailer running lights shouldn't be receiving power unless the running lights in the Ram are on. I'd doublecheck the wiring for the vehicle's running lights to see if power is somehow getting sent to the trailer running lights. You could have a short or knick in the wiring somewhere and it's touching the wire to provides power to the trailer running light fuse, causing the constant power to the trailer running lights.

• 2020 Lincoln Navigator Battery Died After Flat Towing For A Short Distance
• Do you have a charge line installed on the new battery you put in your Navigator? If not, that will definitely explain why the battery died so quickly. You can use the Roadmaster Battery Charge Line Kit # RM-156-25 to run a charge line from the 6-pin to the battery. This way the vehicles battery will be charged by the motorhome. You will also want to make sure the charge line is wired to the center pin of the 6-pin plug since you are using the Blue Ox 7-Wire to 6-Wire Cord # BX88206.

• Troubleshooting Loss Of Function With K-Source Custom Towing Mirrors
• Hey David, The K-Source Custom Flip Out Towing Mirrors # KS60195-96C are a confirmed fit for a 2020 Ram 1500 Classic so that leads me to believe that either the mirrors had a defect from the manufacturer or that there's and issue with the connection between the factory wiring and mirrors. Check to make sure there isn't some sort of debris or even a bent pin in the connectors. If you find nothing then try re connecting the wire harnesses and retest the functions. It could be as simple as...

• Troubleshooting Intermittent Trailer Disconnected Message When Towing
• Hey Bill thanks for your question. Like you said there are several things that can cause an intermittent trailer disconnected message. The most common cause is a rusty or corroded trailer connector. Go ahead and inspect the trailers 7-way plug. If there is noticeable rust or corrosion it will need to be replaced with something like the 7-Way Round RV Style Trailer Connector # A7WCB. I suggest using a bit of Dielectric Grease # 11755 on the trailer plug and the vehicles 7-way. It is ok...

• Determining Wire Functions For A Hopkins Towed Vehicle Wire Harness
• Hey Serge, You would need to reach out to Hopkins directly for the wire function diagram of the # HM56200 or you can disconnect the connectors and test the pins with a tester # PTW2992 with the each specific light function on at a time to see which wire holds which function. If space allows you could also just plug another harness like # 118416 inline with the dinghy wire harness to get a 4-flat for your bike rack.

• Will The Roadmaster Diode Prevent Power From Solar Panels Back-Feeding To Tow Vehicle?
• The Single Diode # RM-690 is going to be a better option than the Diode # RM-790 as it only has the single input rather than a dual input. Ideally your 5th wheel should have come with a In-Vehicle BCDC Battery Charger # RED96FR which would prevent the power from backflowing either from the solar panels or when connected at a campground. If you choose to go with the single diode you want to wire it in line of your 7-way charge line wiring before it enters the Junction Box # 3375601101....

• Troubleshooting Loss Of Trailer Running Light Function On A 2019 Toyota Highlander XLE
• Hey Johnathan, Since you've already checked the fuses and found everything was fine that leads me to believe that the Hopkins Plug-In Simple Wiring Harness # HM11141825 has an internal short. I recommend unplugging it from the factory connector and then turn on your running lights. You can then test the factory connector using a circuit tester # PTW2992 to see if the signal is coming through. If it is then we know the # HM11141825 just needs to be replaced. If the signal isn't coming...

• Troubleshooting Turn Signal Circuits of 7-Way that Have 12 Volts All the Time
• Hey Mark, so what is most likely going on is that there is a short between the 12 volt accessory circuit of your 7-way and the turn signal circuits that are hot all the time. This is most likely due to a problem with the wiring behind connector due to exposed wire and if you inspect and fix that you should be good.

• Solution for Towing 2022 Ford Bronco Sport Behind Motorhome
• The short answer to your question is you don't. The 2022 Ford Bronco Sport states in the owner's manual "You cannot recreational tow your vehicle with all wheels on the ground because vehicle or transmission damage could occur." The Rear, All-Wheel, and Four-Wheel drive models require using a trailer. If you have the Front-Wheel drive model you can use a tow dolly like the Demco Kar Kaddy X # DM9713093.

• Troubleshooting a Curt T-Connector Wiring Harness That Does Not Work
• Sorry to hear about that Michael. There are a couple of basic troubleshooting steps you can do but really the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package # C56357 is plug and play. The first thing I'd check is the ground wire and make sure it's connected to a solid bare metal surface that does not have any dirt or rust. Also make sure the wire isn't damaged or loose. If that's all good check and make sure that the connector is getting the proper 12V needed to operate....

• Troubleshooting Trailer Running Lights Not Working When Connected To One Tow Vehicle But Not Another
• So lets start with the colors for the wiring. White is typically the ground wire for all the different lights. Yellow is the power wire for the left turn signal and left brake light since they are combined. Green is the power wire for the right turn signal and right brake light. And finally brown is for the running lights. Do understand these are the typical colors used and could be different depending on who wired it. Since everything works on the trailer when connected to a different...

• Troubleshooting Lack Of Signal With A Voyager WiSight 2.0 RV Camera System
• Hi Don, Typically if there is a signal issue with a camera system, like your Voyager # ASA84YR, it's a power issue. Most wireless camera systems are wired into the running light circuit or reverse light circuit. If it's wired to the running light circuit then you'll need to turn your running lights on in the tow vehicle. If it's wired to the reverse light circuit the camera will only come on when backing up. If that wasn't the issue then the next step would be to check the voltage running...

• Troubleshooting Lack Of Left Turn/Stop Function On A Trailer
• Hey Marty, When troubleshooting trailer wiring issues the best place to start is the power source. Check that both the left turn/stop function is coming through on your tow vehicle's trailer connector with a tester # PTW2993. If not, you might have a blown fuse and would just need to look through your vehicle's fuse block for the trailer left turn/stop fuse and replace it. From there you can hook up to the trailer and keep testing points in the wire as you make your way to the light...

• Troubleshooting Trailer Brake Light Issue with Curt Wiring Kit on a 2010 Toyota Sienna
• Thanks for the information, Dave! The trouble you're experiencing with the Curt T-Connector # C55580 on your 2010 Toyota Sienna could either be on your trailer directly, or it could be that the converter box has gone out. The best way to figure out which part is the problem is to hook your trailer up to a different vehicle or use a circuit tester # PTW2993 to test the output side of the black box on the Curt wiring. If the trailer side is the problem then you probably have a bad connection...

• Troubleshooting A Curt Towed Vehicle Wiring Harness On A 2023 Jeep Gladiator
• Hi Philip, If just the running lights aren't working then you'll want to start by testing the 4-pole connector on the motorhome to see if the signal is sending out to Gladiator. If not then you could have a short in the wiring somewhere, a blown fuse, or your running lights just aren't turned on in the motorhome. I'd start by making sure that your running lights are turned on in the motorhome. If you're not driving in the dark they probably aren't coming on automatically. You can test...
