Expert Answers about Tow Bar Wiring


  • 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...

  • Flat Tow Wiring for a 2017 Jeep Wrangler
  • The Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit, part # RM-15267, is the best option for you to use to flat tow your 2017 Jeep Wrangler. It will provide a 6-Way wiring harness to the front of your Wrangler that you can connect to the 7-Way on your RV with the included Flexo-Coil cord. If your Wrangler has separate lighting you will need to use a wiring converter, part # 118158, along with 2 additional diodes, part # RM-792, to keep your turn and brake signals separate. If...

  • Installing Roadmaster Diode Wiring Kit # RM-15267 with Separate Wiring on RV and Towed Vehicle
  • If both your motorhome and towed vehicle have a 3-wire system (separate stop and tail lights), then a converter like the Tow Ready # 118158 should not actually be needed. The converter is only needed if your motorhome has a 2-wire system (combined stop and tail lights) and your towed vehicle has the separate, 3-wire system. I have attached a wiring diagram that shows exactly how the kit should be installed for your specific application, where both the motorhome and vehicle have a separate...

  • Recommendation For Tow Lights For 2018 Jeep JL Wrangler Unlimited
  • With a plastic roof on your 2018 Jeep JL Wrangler Unlimited, your wireless tow light options are limited. One option to consider is to stick magnetic wireless lights like the Pilot Magnetic Tow Lights Item # NV-5164 to either the metal side of your 2018 Jeep or to the bumper if it is metal. You will have to experiment with mounting to see if you can get a secure enough hold for the wireless option to be effective. If the side or bumper will not work then I recommend adding something...

  • What is the Correct Wiring Kit to Flat Tow a 2017 Jeep Grand Cherokee
  • The Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56208 that you referenced will fit a 2017 Jeep Cherokee, but is not compatible with your 2017 Jeep Grand Cherokee. A similar wiring kit that is confirmed to fit your Grand Cherokee is the Tow Ready # TR118821. This will operate in much the same way as the Hopkins # HM56208. To complete your flat towing setup you will also need a base plate kit, a tow bar, safety cables, a supplemental braking system, and most likely a...

  • Recommended Custom Tow Bar Wiring Kit for 2019 Jeep Cherokee
  • I do have an option for you, however the Hopkins Custom Tail Light Wiring Kit # HM56208 referenced in your question is not compatible with the new 2019 model Jeep Cherokee. For tow bar wiring I instead recommend the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267. This diode kit lets you wire the Jeep so that it accepts the basic signal lights from your RV while it's being towed. It includes a 6-Way connector that you will mount to the front of the vehicle and enough...

  • Easy Way to Pull Fuse of 2016 Chevy Cruze When Flat Towing
  • There is an easy way to pull the fuses of your 2016 Chevy Cruze when you flat tow it. What you'd want is the Roadmaster FuseMaster part # RM76512. Basically this replaces the fuse in the panel and gives you an easy to access switch to kill and activate the circuit. I attached an install video for this kit on a similar 2017 Chevy Cruze as well. For a base plate kit then you'd want the # RM-523190-5 which is a confirmed fit and I attached an install video for. In addition to the base...

On page 279 of the owner's manual it only specifies that the DLIS fuse from the instrument panel fuse block needs to be pulled. If that is the case then all you need to do is install the Roadmaster FuseMaster Fuse Bypass # RM76511 (see attached video) to make uninstalling the fuse much easier. However, if the dealer is...

  • Recommended Wiring Harness and Parts Needed to Flat Tow 2018 Ford F-150
  • There are a few parts you are going to need to flat tow your 2018 Ford F-150 and for a wiring harness I recommend the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 because it's coiled cord is resistant to water and corrosion, and because it comes with a 6-way and mounting bracket. You will need to use Roadmaster Brake-Lite Relay # RM-88400 as well to keep your 2018 F-150's brake signal from overriding the turn signal sent by your RV The other parts you need are base...

  • Removing Fuses to Flat Tow a 2017 GMC Acadia Limited
  • When a vehicle's owner's manual says to remove fuses I definitely recommend abiding by it. GM requires the fuses be removed in order to disable specific functions that will operate while the Acadia is set up to be flat towed. We do offer products to make the process easier whenever you're setting it up to be towed. The recommended FuseMaster bypass switches for your Acadia are # RM-76517 and # RM76514. Also, for disconnecting the battery with a switch use # RM-766.

  • 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...

  • Flat Towing Lighting Harness Recommendation for 2015 Ford F-150
  • The wiring is different on vehicles that have trailer wiring and ones that do not come with it at all. We see this on other vehicles that will have connections made under the hood and pre-wiring ran to back of some vehicles and on others all of that isn't there at all. In your situation there is a different style of connector than what the part # HM56009 is compatible with. Your truck has a standard round connector since you have the tow package with a factory 7-way. For lighting you...

  • How to Install the Blue Ox Tail Light Wiring Kit on a 2017 Jeep Wrangler
  • In order to install the Blue Ox Tail Light Wiring Kit part # BX8869 in the back of the taillight housing on your 2017 Jeep Wrangler you will need at least 1" of space in order for the bulb and socket kit to work. I did some research and looked at a few of the taillight assemblies for your Jeep and believe you should have absolutely no problem using this kit. 1) Starting in the engine compartment of the towed vehicle, run the 26 ft. harness through the fire wall, under the driver's side...

  • Is Brake Light Relay Needed for 2017 Jeep Wrangler Flat-Towed with Hopkins Harness HM56200
  • Yes, you will need a brake light relay # RM-88400 when using your Brake Buddy Classic with the Hopkins Custom Tail Light Wiring Kit # HM56200. You need to install a relay to ensure that the lights on your towed car always act in accordance with the signals sent by your RV via the wiring harness. Without a relay, the brake signal from your towed car will override the turn signal sent by your RV when you slow down to make turns, creating a potential hazard.

  • How to Keep Blue Ox Patriot II from Draining Battery in 2008 GMC Sierra 1500
  • Since the Hopkins Custom Tail Light Wiring Kit # HM56101 has built-in diodes you will not get any feedback through the wiring. No additional wiring or kit is required to keep that from happening. Depending on how far you are traveling and how much braking you are doing, it could be possible that the Blue Ox Patriot II # BRK2016 would drain your battery, especially if the ignition key has to be left in the on position. To help eliminate the possibility of your battery becoming drained...

  • Tow Bar Wiring Harness Recommendation for 2016 Jeep JK Unlimited Rubicon
  • I have a great solution for you but the Trailermate harness part # TM781124 does not carry over to the 2016 Jeep Wrangler Unlimited. Instead the Hopkins kit part # HM56200 is a fit and would be the better option. I attached an install video for this kit on a 2016 Wrangler Unlimited like what you have as well. The part # 787196 will go from a 7-way to a 4-way like you said you needed as well. It's coiled so it's easy to wrap around the arms of your tow bar.

  • Wiring Harness for a 2017 Ford Edge SEL to Tow a Trailer and to be Towed Behind a Motorhome
  • The wiring harness that you need to tow a trailer with your 2017 Ford Edge SEL (or for any vehicle for that matter) will be different than the harness that you will need to be able to tow your Edge behind your motorhome. The Hopkins Custom Tail Light Wiring Kit # HM56011 that you mentioned will not fit your Edge. Instead you need to use magnetic lights like the Pilot # NV-5164.

  • Parts Needed to Connect Vehicle with 4-Pole to Trailer with 6-Way and Separate Brake Lights

Your Brown running light wire will simple bypass the converter and go directly to the trailer connector. Rather than use adapters to connect the tow vehicle and trailer I suggest you wire in a matching...

You do need supplemental braking though as well. The easiest system to set up and use is the Blue Ox Patriot # BRK2016, that applies the vehicle brakes in proportion to how much the tow vehicle is braking. This is the safest way to stop and it reduces wear and tear on both vehicles.

  • Towing a US Trailer with 4-Way with an Australian Vehicle with 7-Way Flat Connector
  • The best way to get a US trailer to work with a separate wiring system is to go ahead and just add amber turn signals to the trailer. That way you just need the 2 turn signal lights and the proper trailer side connector to match the one on the tow vehicle. Converter # 118158 would not be needed. I have linked the lights we have that can be used as turn signals. The other way would be to combine the circuits on the tow vehicle and install a 4-Way flat connector on it to match the trailer...

  • Availability of Tow Bar Umbilical Style Adapter to Go From 4-Way Flat to 7-Way Blade
  • Yes, for a tow bar umbilical extension adapter to go between the 4-way flat of the part # HM56304 and a 7-way socket you'd want the Wesbar adapter part # 787196. This has a 5-way flat on one end and a 7-way blade connector on other. The difference between a 5-way and a 4-way is just the extra pin on the outside of the connector.

If you have the ground attached to a clean, bare metal surface and do not have a current showing on the brake circuit, the harness may need to be replaced. If you show current at the connector, the problem lies either...

  • How to Use the Roadmaster Brite-Lite Wiring Converter with LED Lights
  • I am not quite sure I understand what you mean. A relay does not regulate voltage, that is what a resistor is for. A resistor is more often than not required when using LED lights as the lower current draw can trick the system into thinking there is a short which will then send a pulse to the lights causing hyper flash. If you are in fact referring to the relays then I would not have a wiring diagram for this as each are different and will need to be wired according to the pin out which...

  • Why are Diodes Needed for Lighting when Flat Towing a Vehicle
  • When a vehicle is being towed it cannot operate its own lights. The diodes are a gateway with 2 inputs and one output. One input is the regular wiring on the vehicle. The other input is from the RV. Since vehicles being flat towed will not have working lights they will have to get power to function from the RV. The diodes allow for 2 inputs so that you don't have to disconnect the vehicle lights to plug in power wires from the RV. The tow vehicle lighting system only matters if the tow...
