2012 Ford Fiesta - Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles - 7-Wire to 6-Wire Straight Cord

This complete kit includes everything you need to connect your RV's tail, brake, and turn signal lights to your towed car. Diodes prevent feedback and wire your car to operate as a combined system. Includes a 7-way to 6-way straight adapter cord.


Features:

  • Complete wiring kit lets you connect your RV's tail, brake, and turn signal lights to your towed Ford Fiesta's lighting system
    • Wires towed car as a combined lighting system so that brake and turn signals travel along same wire
  • Diodes prevent electrical feedback and the damage it can cause to your car's electrical components
  • 7-Wire to 6-wire adapter cord allows you to run power from your RV to your towed Ford Fiesta
    • Straight cord is ideal for all-terrain tow bars and other tow bars that have channel guides
  • 6-Way socket wires to harness and mounts on towed car with included bracket
  • Sturdy, durable construction
    • Powder-coated aluminum casings protect diodes from corrosion
    • Electrical cord resists water, oil and chemicals
    • Silicone-injected plugs prevent corrosion
  • Kit includes:
    • 4 Hy-Power diodes
    • Wiring harness
    • 7-Way to 6-way adapter cord
    • 6-Way socket with mounting bracket
    • Wire connectors
    • Cable ties
    • 1 Ring terminal
    • 3' Long plastic loom
  • Brake light relay (RM-88400 - sold separately) may be required if used with supplemental braking system


Specs:

  • Maximum amperage: 85 amps
  • Maximum voltage: 24 volts
  • Adapter cord length: 6-1/2'
    • Wire gauge: 16
  • Wiring harness length: 30'


Note: For applications that have separate lighting, this kit will cause your brake lights to function as both brake and turn signal lights. A wiring converter (118158 - sold separately) and 2 additional diodes will be needed if you want to retain separate turn and brake signals.


Separate vs. Combined Lighting Systems

Some automobiles operate on a 3-wire system, wherein the brake signal and the turn signals travel along different wires to illuminate different lights. (Typically, these Ford Fiestas have amber turn signals.) This is referred to as a "separate lighting system". When you hook up for flat towing using this kit, your towed car's lighting system will operate in a combined fashion regardless of whether it typically has combined or separate lighting. This means that the brake and turn signals sent by your RV to your towed car will be carried on a single wire. As a result, your car's brake lights will do the flashing for the turn signals. Your Ford Fiesta will still function as designed when not hooked up to your RV.

Do You Need a Brake Light Relay?

Because this kit wires your Ford Fiesta as a combined system, a brake light relay (RM-88400 - sold separately) may be required if you use a supplemental braking system with your towing setup. A supplemental braking system depresses the brake pedal in your towed car every time you apply the brakes in your RV. So, if your towed car's brake lights illuminate when the brake pedal is pressed and the engine is off - as is the case when towing - then 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.

Video Transcript for Roadmaster Tow Bar Wiring RM-152-98146-7 Review

Speaker 1: Today we're going to take a look at the Roadmaster four diode universal wiring kit for towed vehicles, with the 7-wire to 6-wire straight cord. Now, this is a complete wiring kit, which'll let you connect your RV's tail, brake, and turn signal lights to your towed vehicle's lighting system. This kit will wire the towed car as a combined lighting system, so that the brake and turn signals traveling along the same wire.This kit will include everything laid out here on the table. Start with the four high powered diodes, 30 foot long wiring harness, three foot long plastic loom. Over here we have the 6-1/2 foot long 7-way to 6-way adaptor cord with the 6-way plug. Does have the 6-way socket with the mounting bracket.

Some wiring connectors, a ring terminal, and some cable ties to take up any slack in the wiring.Now the diodes, these'll prevent the electrical feedback, and the damage it can cause to your car's electrical component. They use powder coated aluminum casings to protect the diodes from corrosion. Over here, we have the 7-wire to 6-wire adaptor cord, which allows you to run power from your RV to your towed vehicle. And it's a straight cord, so it's ideal for all terrain tow bars, and other tow bars that have channel guides. The 6-way socket here, that the 6-way would plug into, this will wire to the harness, and it mounts on your towed car using this included mounting bracket with some hardware.Now this is a sturdy durable construction.

The electrical cord will resist water, oil, and chemicals. And the silicone injected plugs to prevent corrosion. Now a brake light relay may be required, if you're used with supplemental braking system. We do sell the relay separately on our website. It's part number RM-88400.

A few specs on this, the maximum amperage is 85 amps. Maximum voltage, 24 volts. The adaptor cord length here is 6-1/2 feet long. Wire gauge they use is 16 gauge. And a wiring harness length is 30 feet long.One last note, and it does come with some nice instructions on how to install everything.

But one last note I do want to mention, is for an application that has separate lighting, this kit will cause your brake lights to function as both brake and turn signal lights. If you do want to retain the separate turn and brake signals, it will require a wiring converter, part number 118158, that we sell separately on our website. And two additional diodes will be needed if you want to retain the separate turn and brake signals.But that should do it for the review on the Roadmaster four diode universal wiring kit for towed vehicles with the 7-wire to 6-wire straight cord.

Do you have a question about this Tow Bar Wiring?


  • Recommended Flat Towing Components For A 2017 Ford F-250
  • In order to flat tow your 2017 Ford F-250 behind a motorhome, you will need the following items: Base Plate Kit, Tow Bar, Wiring Harness, Safety Cables, Supplemental Braking System, and Possible High-Low Adapter. I have attached my recommendation for each of the following items below. For a base plate kit that will work well for your vehicle, I recommend using the Roadmaster EZ5 Base Plate Kit part # RM-524452-5 as this is Roadmaster's most advanced removable arm base plate kit.

  • Parts Needed to Flat Tow a 2015 Smart fortwo Behind an RV Using Roadmaster Tracker Tow Bar
  • To use the Roadmaster Tracker tow bar # RM-020 with your 2015 Smart fortwo you will need base plates # 52285-1. If you want to be able to remove the crossbar from the tow bar then you would also need to use quick disconnects # RM-201. In addition to the tow bar and base plates there are a few other items needed to properly and safely flat tow the vehicle. First you will need some safety cables, # RM-643. The coiled design helps keep the cables off of the ground. Next you will need...

  • Can the Roadmaster Kit # RM-152-98146-7 Run Through the Side Channel of Falcon All Terrain II
  • The wiring for the Roadmaster 4-Diode Universal Wiring Kit # RM-152-98146-7 that you referenced will feed through the side channel of your Falcon All-Terrain II but if you are needing more length than the 6-1/2' cord I have another solution for you. The Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 is the exact same thing except that it has a coiled cord instead of a straight one. The coiled design keeps it from dragging on the ground when you are flat towing. When...

  • How to Tow a 2019 Jeep Cherokee Behind a Motorhome
  • You can flat tow the 2019 Jeep Cherokee if it is a 4x4 model with 2-speed power transfer unit. Models with the 1-speed power transfer unit would have to be put on a trailer. None of the 2-wheel drive models can be flat towed but you can dolly tow front wheel drive models from the front. If you do have a model that can be flat towed and it is a Trailhawk or Overland edition you can use base plates # RM-521451-5. For a compatible tow bar I recommend the Falcon All-Terrain # RM-522.

  • The equipment that you will need to flat tow your 2017 Ram 3500 includes a Base Plate Kit, Tow Bar, Safety Cables, Tow Bar Wiring, a Supplemental Braking System, and most likely a High-Low Adapter. For a Base Plate Kit I recommend using the Blue Ox # BX1989 which will bolt securely to your chassis. The Tow Bar that I recommend going with is the Blue Ox Avail Tow Bar # BX7420 which is rated for 10,000 lbs and comes with Safety Cables. I recommend installing the Roadmaster 4-Diode...

  • How to Dinghy Tow a 2017 Nissan Versa
  • According to page 10-17 in the online version of the owner's manual for your 2017 Nissan Versa, if the vehicle has a manual transmission then it can be flat-towed with four wheels down but if it has an automatic or continuous variable transmission (CVT), it must be towed using a tow dolly under the drive wheels. If you have the automatic or CVT transmission then I recommend the Roadmaster Tow Dolly part # RM-2000-1. This dolly has self-steering wheels to improve maneuvering and electric...

You can see everything that is included with this base plate kit in the attached photo. The Blue Ox Tail Light Wiring Kit part # BX8869 will work for you as long as you do not have LED tailights.

  • Parts Needed to Flat Tow a 2018 GMC Sierra 1500 Behind a Motorhome
  • We do have base plates for your 2018 GMC Sierra 1500 but # RM-3180-2 will not fit. The comparable set that will fit your 1500 is # RM-3177-3. This set actually has removable arms so that when you take them out the base plates are essentially invisible. I have linked the installation instructions for you to view. For a compatible tow bar I recommend the Blackhawk 2 # RM-422. This is an all-terrain tow bar which means you will not have to be lined up perfectly straight and level to hook...

  • I checked with Roadmaster and they do show the diode kit # RM-154 as a fit for the 2017 Ford F-150. They also show that you can use kit # RM-152-98146-7, # RM-15267, or # RM-15247 as well. I have linked a video showing a diode system being installed on a 2016 Ford F-150 and it will be similar on a 2017.

  • Adapter to Flat Tow a 2009 Jeep Wrangler with Aftermarket Bumper with D-Rings
  • We do have adapters so that the D ring bumper on your 2009 Jeep Wrangler will be compatible with a tow bar, but you will need a new tow bar. The adapters that will allow you to flat tow your Wrangler come from Roadmaster. Blue Ox tow bars and Roadmaster base plate kits already require an adapter to be used together. The adapter for your bumper is not compatible with the Roadmaster Base Plate/Blue Ox Tow Bar adapters. The Roadmaster Adapter # RM-035 will attach to 3/4 inch shackle mounts...
