Expert Answers about Tow Bar Wiring


  • Recommended Wiring to Flat Tow 2020 Jeep Wrangler Behind Motorhome
  • To wire up your 2020 Jeep Wrangler so that it accepts the signal lights from your RV I highly recommend the Roadmaster Diode Flexo-Coil Wiring Kit # RM-15267. This will tap into the tail light circuits of the Jeep and provide you with a 6-Way to mount at the front, along with enough coiled wiring to go from there to the 7-Way on the motorhome. The included diodes prevent any potentially harmful feedback. I have attached an installation video on an earlier model Wrangler that you can...

  • Wiring to Flat Tow a 2019 Jeep Wrangler Behind a Motorhome
  • Magnetic tow lights, like part # TL21RK, do their job just fine, are less expensive, and don't require much to setup so they're not a bad option by any means. The only real drawbacks to them is that you need to set them up or take them off each time you change from towing to driving the Jeep. They also have a chance of scratching the Jeep's paint since they're being attached to its surface each time. We often recommend them if you're not going to be towing the vehicle very often or if...

  • Plug and Play Lights for Flat Towing 2019 Jeep Wrangler Unlimited
  • There is one plug and play option for lights when you are flat towing your 2019 Jeep Wrangler Unlimited, although it would use magnetic lights as opposed to the Jeep's lights. You would need the Pilot Magnetic Tow Lights - 4-Way Flat and 7-Way RV Connector - Wireless # NV-5164 which will plug into your Jeep's 4-way or 7-way to send signals to the mounted lights when you turn or brake. To use your Jeep's lights you'll need to splice into the wiring with the Roadmaster Diode 7-Wire to...

  • Flat Tow Wiring Needed For 2020 Jeep Wrangler
  • The best option for flat tow wiring on the 2020 Jeep Wrangler is Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit part # RM-15267. This will provide a 6-Way round harness on the front of the Jeep Wrangler that you can to your RV with the included flexible coiled cable. If you are planning on using a supplemental braking system, you will need a stop light switch kit part # RM-751490 which will alert you when the Wranger's brakes are being applied while flat towing. To complete...

It looks like you're getting your 2016 Kia Soul ready for flat towing, which is a rather large undertaking, but we're here to help make that as easy as possible.

  • Heavy Duty Magnetic Towing Lights for Flatbed Trailer Towed by 2017 Ford F-350
  • It sounds like you're trying to add some lights to a flat bed trailer being towed by a 2017 Ford F-350. If your 2017 Ford F-350 has a 4 way round pin plug installed (or you're willing to do some wiring), you can use the Heavy Duty Magnetic Tow Lights # 337TL257M which comes with a 4 way round pin plug and socket to install on your vehicle. With that being said, I have a solution for you that won't require any additional wiring work. I recommend using the Heavy Duty Magnetic Tow Lights...

  • Replacing Malfunctioning Flat Towing Wiring Harness on 2014 Jeep Wrangler
  • From what you describe, the the relays in the converter are going bad, and my contact at Hopkins agrees. The relays aren't readily accessible and aren't designed to be replaceable, so your best bet would be to replace the # HM56200 harness entirely. Or, you could go in a different direction with a more reliable hardwired system like the # RM-15267 from Roadmaster. Installation of this product would mean tapping into the wiring harnesses for the taillights of your Jeep, but this installation...

  • Does Brake Buddy Select Supplemental Braking System Drain Vehicle Battery
  • The Brake Buddy Select 3 part # HM39524 like you have plugs into a power outlet in the tow vehicle to power the brake setup. So what that means is that it's draining your vehicle battery as it's being used. Using a fuse bypass won't prevent this from happening. Only solution is a battery charge kit like the part # RM-156-25 like it sounds like you tried which will keep the battery topped off so that when it's being used it will hopefully recharge.

  • Installation of Tow Ready TR118821 Flat Towing Wiring Harness on 2020 Jeep Gladiator
  • If the 4-pole/7-way on your Gladiator is already functional, you wouldn't need to add a 4 pole harness like the Curt # C56407. Adding the flat towing wiring harness like the # TR118821 wouldn't interfere with the factory trailer tow wiring. I've provided a wiring diagram showing how the # TR118821 installs as well as to a video showing a typical installation.

If so the circuits are already combined regardless of what you see on the vehicle taillights. If you plan to use a diode kit or bulb and socket tow bar lighting solution you will need a brake light relay like # RM-88400 when using the brake system you mentioned so that the brake lights won't override the blinkers. It's a toss up on which is easier to use between the Roadmaster...

  • Can I Purchase Roadmaster Diode Kit Without The Coiled Adapter

This 6-way plug is the same plug that comes with the kit # RM-15267. The Diode kit part # RM-152 comes with 4 diodes and 30 feet of 4-wire. It also comes with the connectors, zip ties, 1 ring terminal and plastic loom to wire the vehicle for lights while flat towing. I have attached an installation video of the diode kit in...

  • Can Hopkins HM56202 be Wired into 6-Way Connector on Front of Towed Vehicle
  • Absolutely! We actually recommend doing this exact install a lot of the time. Using a 6-way, like part # PK12720 for an example, at the vehicle's front allows you to install additional wiring for a braking system or charge line but doing it this way makes it an easier install because the Hopkins # HM56202 is the easiest to install harness for your 2004 Jeep.

  • Using C56407 Trailer Wiring w/ TR118821 Taillight Diode System While Flat Towing 2019 Jeep Wrangler
  • In order to install the # TR118821, you will need to do a little splicing but the easiest and safest way to do that would be to tap into the wires on the Curt # C56407, the procedure for this is shown in the instructions for the # TR118821, which I've linked for you. Installing in this manner will not harm the trailer wiring harness in any way. I've linked to some videos that you might find helpful.

  • I do have a great lighting solution for you, however the Hopkins Custom Tail Light Wiring Kit # HM56200 that you referenced won't work on your 2020 Jeep Wrangler Unlimited. This custom harness is designed to fit earlier model Wranglers (up through the 2018 model year) and isn't compatible with the new generation.

It simply plugs into your factory wiring connections at your tail lights and is run to the front of your vehicle for connection to your towing vehicle.

If you are using the Curt 2-To-3-Wire Tail Light Converter # C56196 in conjunction with a wiring kit like the Tow Ready # TR118821 it should work properly to isolate the 3rd brake light signal but you need to make sure that you are connecting the right and left turn wires to something on the output side.

They both do the same thing. The white input wire is ground (earth), yellow is combined left turn signal and brake light, and green is combined right turn and brake light. On the output side you will have the yellow wire for left turn signal only, green for right turn signal only, and red for brake...

The Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 is a more 'universal' kit that focuses on giving you a 7-wire to 6-wire harness no matter what tow bar you have.

  • Fuse Bypasses Needed to Flat Tow a 2016 Chevy Traverse
  • Both bypass switches are needed in order for you to flat tow your 2016 Chevrolet Traverse; the reason for that is because they are different types of fuses (at different locations, as you pointed out), so both switches are needed, the Roadmaster FuseMaster Fuse Bypass Switch - 50 Amp FMX Fuse # RM-76517 and Roadmaster FuseMaster Fuse Bypass Switch - (2) 20-Amp ATC/ATO Fuses # RM76514. I have added links to video installations of both bypasses being installed on a 2016 Traverse for you...

  • How Many Hours Will the Custer Wireless LED Light Battery Last Between Charges
  • The Custer Wireless LED Tow Bar Light # LIW-LDTL has a 4-8 hours battery life before it would need to be charged, so it's not really ideal for the use that you're looking for. With that said, if you could figure out a way to keep it plugged in to a 12v power source inside the tow vehicle you could likely make this work as you're hoping. However, if you wanted a set of removable lights that work with a wireless signal, you may want to have a look at the Pilot Magnetic Tow Lights - Red...
