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.

  • Pulling Fuses to Flat Tow a 2019 Chevy Sonic
  • From my research you're correct, fuses need to be removed in order to flat tow your 2019 Chevy Sonic. It sounds like the same is true for the 2018 model as well. You can remove them and insert them manually each time you tow or we sell fuse bypasses from Roadmaster called the FuseMaster. The FuseMaster installs permanently in the Sonic and makes "removing" the fuse as easy as flipping a switch. This bypasses the fuse without actually having to take it out each time you tow. If...

  • 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.

  • 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.

  • Is Brake Lite Relay Needed When Installing Tow Bar Lighting in 2018 Jeep JK Wrangler
  • What braking system are you planning on using? If the system presses the brake pedal of the 2018 Jeep JK Wrangler like most do then yes you do need to use the # RM-88400. The reason for this is so that the stoplights of your Wrangler don't override the blinker circuits of the # RM-15267. I attached install videos for both kits in similar 2017 Jeep Wrangler Unlimiteds.

Please keep in mind that you will also need to disconnect your Silverado's battery when towing and the Roadmaster Automatic Battery Disconnect # RM-766 is highly recommended to make this process easier.

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...

When answering questions like this we always consult with the vehicle's owner's manual so it's likely that since the vehicle's release the manual has been updated to separate out the different engine types with regards to recreational towing.

  • How to Isolate Stop Light Signal for 3rd Brake Light on 2017 Ford Fusion
  • Thank you for all of the information about the wiring you are using for flat towing your 2017 Ford Fusion. 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.

  • Separating Out a Combined Brake Light and Turn Signal to Have Separate Turn Signals and Brake Lights
  • We do have converters that do separate out the combined brake light and turn signal but # TR118821 is not one of them. What you can use instead is tail light converter # 118158 or # C56196. 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...

  • How To Add Third LED Brake Light On Trailer
  • If you would like to add a third brake light that is LED I recommend to use the Curt 2-To-3-Wire Tail Light Converter part # C56196 because it is more compatible with LED lights in our experience compared to the Tow Ready version part # 118158. Since your trailer has a combined wiring system the the converter will separate it so the third brake light will only come on when braking. I also recommend to use diodes to prevent feedback with Roadmaster Single Park Light Diode part # RM-690....

  • Is Brake Light Relay Required w/Hopkins Tow Bar Wiring & SMI Stay-IN-Play DUO on 2017 Jeep Wrangler
  • Yes, if you were to use anything other than a magnetic light kit on your 2017 Jeep Wrangler Unlimited you will need to use the brake light relay # RM-88400. The relay is meant to prevent the Jeep's brake signal for overriding the turn signal coming from the tow vehicle/RV when applying the brakes with a turn signal on. So if you use the Hopkins wiring harness # HM56200 you will need to use the brake light relay. I have included a link to a video showing an example installation of the...

  • Comparing Tow Ready and Roadmaster Diode Wiring Kits for Flat Towing
  • The biggest difference between the Tow Ready Tail Light Isolating Diode System # TR118821 and the Roadmaster Universal Hy-Power Diode Wiring Kit # RM-154 is that Tow Ready created their wiring kit with quick disconnects so if you ever get a new vehicle you can take the kit with you. The Roadmaster option can also be removed but you would have to splice all of the wiring again as the quick disconnects don't match up the way the Tow Ready option does. Both are great options and I'm sure...

  • 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.
