2001 Chevrolet Express Van - Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles - 7-Way to 6-Wire Hybrid Cord

  • Diode Kit
  • Splices into Vehicle Wiring
  • Universal
  • Roadmaster

Perfect for tow bars with built-in channels, 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.


Features:

  • Complete wiring kit lets you connect your RV's tail, brake, and turn signal lights to your towed vehicle'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 vehicle
    • Hybrid cord is ideal for all-terrain tow bars and other tow bars that have channel guides
    • Coiled end connects to RV and prevents cord from dragging and tangling
    • Straight end connects to towed vehicle and is ideal for tow bars with 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
  • Limited Lifetime Warranty


Specs:

  • Maximum amperage: 85 amps
  • Maximum voltage: 24 volts
  • Adapter cord length: 8'
    • 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 vehicles 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 vehicle will still function as designed when not hooked up to your RV.

Do You Need a Brake Light Relay?

Because this kit wires your vehicle 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.

My E-trailer experience was outstanding! From the great selection guide to the delivery to the installation support. The installation videos were very helpful. I had two installation issues that were answered with a prompt phone call. One call was on a Saturday morning. I highly recommend E-trailer!



by:

Highly recommend E-Trailer for all of your towing accessories. Great product, great customer service!!



by: 04/08/2021

So far so good. Self installed on 2018 Ford F150. RV side was a breeze. Written instructions are weak. The truck side included economy wiring kit which required cutting tailight and brakelight wires in order to tap diods into lines. If doing it again, I would order the Hopkins custom wiring kit HM56009. It doesn't require cutting wires. It plugs into factory connections.



by:

Works great! A bit difficult to install but once you understand the concept it's easy.



by:

The plug in to auto did not work, had to get another. Being that it is enclosed within unit wrapping, I JUST HAD TO TIE IT UP FOR TRAVEL. so ITS functionality, side lights did not work also. Finally it is quite heavy. Overall stay away from this unit.

Thank you for reaching out! This item has a limited lifetime warranty and I have sent that information along to you.



by:

Works good,easy to install.



by:

Works fine to connect our tow car to the RV



by:

Wiring kit is a must have. What keeps me from giving it 5 stars is the fact that you need to use butt connectors to connect to truck wiring harness. Best would be to have plug and play connectors or this wiring harness.



by:

Cord no longer works when using the left directional light.



by:

I don’t think my installer got it right. Brake lights override the turn signals. Everything else works great.

Does what it is intended to do. Took a little time to install but it came with all the instructions I required, and it all looks and works great!

Little time consuming to do put all good things take time

Works great!!! Just finished a 7,900 mile loop around the US, and they performed flawlessly.



by:

Excellent product

Install was straightforward. I installed on a 370z. I have three issues though:1.the wire end connects are not heat shrink (using a heat gun) so I added heat shrink tubing. 2: the wire is too short. I snaked the wire through the interior and it ended up being about 6 inches too short so I had to splice additional wire (which hacks me off), and 3. The wire loom is too short. Not enough to fit between the taillights. No issues with etrailer but seems that Roadmaster could have spared just a bit more expense for a better install.



by:

Wow!!! So very impressed with this company!!’ Haley helped me by phone make sure everything I ordered was right for my RV and Smartcar (tow bar, base plate, battery shutoff and wiring). It came quick and the quality of the products (Blue Ox) are outstanding. Highly recommend this company!! Thank you for helping me!!

Realitively easy to install. Just understanding the best way to route the wire.

Worked well just like video, snaked wire thru divers side frame to behind wheel well and run to front of jeep, was a little time consuming not having a lift.

worked out fine. But I was sent 3 harnesses and had to remove the one from the tow bar.

  • What Parts do I Need to Flat-Tow My 2022 Jeep Gladiator with Factory Steel Bumper?
    If you have a factory steel bumper on a 2022 Jeep Gladiator Rubicon with a factory steel bumper, you need a base plate, a tow bar, a tow braking system, safety cables, and vehicle tow wiring. You also need additional parts for the battery charger kit. For that setup, I recommend the following parts: - Blue Ox Base Plate Kit - Removable Arms # BLU53FR - Roadmaster Falcon 2 Tow Bar for Blue Ox Base Plates - Motorhome Mount - 2" Hitch # RM-525 - RoadMaster 68" Single Hook, Coiled Safety...

  • Parts Needed For Flat Towing a 1995 Jeep Wrangler YJ With Blue Ox Alpha 2 Tow Bars

Both the kits above will accept the Blue Ox Alpha 2 Non-Binding Tow Bar # BX7380 without any adapters. You will need the Roadmaster...

  • Best Tow Bar For Blue Ox Base Plates on 2021 Ford Escape Hybrid
