Video Transcript for A Closer Look at the Roadmaster Hy-Power Diodes (Qty 4)

Speaker 1: Today we're going to take a look at the Roadmaster heavy duty Hy-Power diodes for a quantity of four. Now, this will allow motor homes or RVs to power the lights on the tow vehicle without power feedback. The diodes will permit electrical current to flow in only one direction, from the motor home to the car, preventing any electrical feedback and the damage that it can cause to the tow car's electrical components.This part is for a quantity of four diodes with the 12 spade terminals included to hook this up. It is a heat sink design on the diode and this does reduce wiring hassles. It's a trouble-free operation. It does include detail wiring instructions on the back here, and the maximum load is 85 amps per diode.

That should do it for the review on the Roadmaster heavy duty Hy-Power diodes for a quantity of four.

Exactly what I needed for my Ram 2021 Truck to flat tow



by:

Shipping was fast, product worked as ad vertised.



by:

Product looks like good quality. Seems to be plenty of instructions on line to assure a successful installation.



by:

The diodes are great, but the wiring term. should be weather seal type.



by:

Product fit great. Superfast shipping and great communication!



by:

These little beauties perform exactly as described. e trailer is a great company to deal with. I highly recommend them!



by:

Installing Baseplate an wire tailites for towinginstructions were great,the plate fit very good. The diodes work fine but wireing a ford edge for towing was hard an room for the diodes back of the tailites was very limited .I would very highly recomend your products



by:

Product was exactly as described and the shipping was very fast. Got the item as stated.



by:

This is a solid product. The package had sufficient instructions for installation by someone who had never installed the diodes before.



by:

The wrong one originally sent. Roadmaster gave me this part number so I could order the correct ones. They work as advertised.



by:

Wired up 2012 Jeep JKU for towing behind RV. These 4 diodes worked perfectly! Watched trailer video, it was easy.



by:

Roadmaster makes great quality products, and Stacey A is great to work with!



by:

Worked perfectly



by:

Easy to install in-line of your towed vehicle. Use your toad's own lighting and eliminate magnet sets or additional lighting installs. As easy as wiring a trailer. Make towing your toad as simple as possible. You owe it to yourself.



by:

Fair price, delivered as agreed on time. Would buy again from this vendor.
Only reason I did not give this five stars is that I have yet to actually hook them up in the wiring system to enable my factory lights on the towed vehicle to be operational when taken on a trip behind my RV.



by:

Diodes work as designed. They eliminate additional lights and prevent the need to drill a hole in the tail light assembly. I used these on a previous vehicle and they are still problem free after eight years.



by:

perfect for my project -- using to tie flood lamps to rear of fire apparatus to use in conjunction with back up lamps and separately use the floodlights to be switched at the back of the apparatus



by:

I've used this product several times over the years and found the best price for this quality product here at Etrailer.com. The service was great with fast shipping and no damage to my items.

I'll definitely buy for them again.

The base plate is easy to use and looks great on our MKX. The installation videos are very detailed and precise.



by:

Works as expected. Only problem plugging electric to car sometimes not so great .Overall the Sterling setup is wonderful .

Worked great as it should ,some times plug elec.lines not so good



by:

i installed this product in my golf cart because when i have to load the golf cart onto the trailer to take it to get repaired i can connect the golf cart to the truck and the trailer lights to the connecter at the back of the golf cart so that all the lights work



by:

I installed these diodes on my wifes 2006 VW Jetta TDI to isolate the signal and tail light system from my tow vehicle. The system works as planned and the quality of the parts are excellent!

VW/Audi products are notorious for system glitches when you drive the stock lights with a tow vehicle. I routed standalone wires from the front bumper mounted bulkhead plug to the rear of the car down the inside of the drivers side rocker panel and into the trunk area.



by:

I have used these in the past so when i got a new tow vehicle i bought them again.
They make wiring up the lights on a tow vehicle a snap. I have never had one fail.

  • Troubleshooting Flat Tow Wiring and RoadMaster Invisibrake System on a 2025 Jeep Wrangler Sahara
    Thanks for reaching out Chris, happy to help! The Curt Custom Tail Light Wiring Kit # C96JR does have diode protection for the tow wiring, so we would not recommend adding the Roadmaster 4-Diode Kit # RM-794. From what you're describing, it sounds like the InvisiBrake is seeing a brake light signal from the Jeep and interpreting it as a command to activate. The Roadmaster Brake Light Switch Kit # RM-751490 would be the better option to look at. This kit adds a dedicated brake pedal...

  • Tow Bar Wiring/Lighting Kit for 2001 Dodge Dakota with Charge Line for Battery
    The tow bar lighting solution you would want for your 2001 Dodge Dakota would be the Roadmaster diode kit part # RM-152-98146-7 which will give you the lighting functions for the truck as well as carries an extra circuit you can use for charging the Dakota battery. Then to complete the charge line to your Dakota battery you'd want the part # RM-156-25 as well and you'd be set.

  • Flat Tow Wiring Kit Compatible with 2005 Honda Pilot
    The TowDaddy Custom Tail Light Wiring Kit for Towed Vehicles # TD3018 is not a fit for your 2005 Honda Pilot. TowDaddy was acquired by Hopkins, but they no longer make these harnesses and I do not recommend them. Hopkins does make some custom wiring connection harnesses but unfortunately they do not make one for your Pilot. For a better alternative I recommend the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 or the Roadmaster Universal Hy-Power Diode Wiring Kit...

  • Are the Roadmaster Hy-Power Diodes Water Tight
    As long as you are not exceeding the 85 amps at 12 volts per diode max load then you can definitely use the configuration in your diagram. I spoke with my contact at Roadmaster who said that the connections are not watertight but the internal components are. You would either need to find a way to make the connections watertight (as you mentioned in your diagram) or simply wipe the connections off if you were to go off-road with your 2011 Jeep Wrangler and get the diode(s) wet. We have...

  • Where to Install Diodes when Installing Roadmaster Invisibrake with Tow Bar Lighting
    If you check out the picture I attached you will see where to install the diodes on your vehicle to install both the Roadmaster InvisiBrake Supplemental Braking System # RM-8700 and the part # HM56304 that you referenced. For a diode kit you would want the part # RM-794.

  • Is Using The Hy-Power Roadmaster Diodes Better or Worse Than The Smart Diodes on 2021 Chevy Colorado
    First the biggest difference is the cost of the Hy-Power Diodes # RM-794 being more price conscious than the Roadmaster Smart Diodes # RO34FR. The Hy-Power diodes will also allow you to tie into the 2 separate functions on the incandescent bulb where the smart diodes only have one output and regulates power going into the single function of the incandescent bulb. So if this filament inside the bulb were to fail neither light would work where as with the Hy-Power if the brake/turn filament...

  • Are Diodes Needed For Installing Roadmaster InvisiBrake on Jeep Wrangler
    Appreciate the purchase and yes, you will need diodes for your Jeep Wrangler when installing the Roadmaster InvisiBrake Supplemental Braking System # RM-8700. Per Roadmaster, even with a plug-in wiring harness like you have, you would still need to install diodes, and for that use the Roadmaster Hy-Power Diodes # RM-794.

  • Does Roadmaster Hy-Power Diode Have Any Voltage Drop
    The Roadmaster Hy-Power Diodes haven't been tested for voltage drop since they are designed to be a pass-thru device that just keeps backfeeding from happening. When I reached out to my contact at Roadmaster they said that the voltage drop would be very minimal if anything. I like the Hy-Power Diodes because of how durable and effective they are. You can get this diode in a handful of qunatities: 1 - # RM-790 2 - # RM-792 3 - # RM-793 4 - # RM-794

  • Winnebago with Seperate Taillights Towing a Jeep and Troubleshooting Brake Lights not Working
    Since you have connected your Winnebago to both your Jeep and boat trailer and are experiencing the same issue it is likely related to the vehicle wiring on your Winnebago that is the issue. The first thing that I would check would be the vehicle connection 6-way on your Winnebago and make sure that all the wiring to the connection points are in-tact and that the pins do not show any signs of corrosion or damage. You will want to use a circuit tester like part # PTW2993 to test the...

  • Connector and Diagram to Convert UK Land Rover Defender to US 7-Way Trailer Connector
    Yes, we do have a diagram you can reference when installing a US-style 7-Way on your Land Rover Defender, like the Hopkins Endurance # HM47210. I'm attaching a photo showing the pin-out for a US 7-Way and I'll be linking our helpful article that goes into this with a little more depth. Please note that vehicle wiring in the UK tends to be separated out a lot more than in the US so you may end up needing to use some other parts like the Roadmaster Hy-Power Diodes # RM-794 as well.

  • Can 2013 Fiat 500 with Separate Taillights be Wired for Flat Towing with Diodes for Combined
    Your situation is a very common one and the solution you proposed is the easiest and most popular solution. Like you mentioned you'd be wiring up the separate taillights to function like combined ones. You'd need a total of 4 diodes which we have that as a 4 pack with part # RM-794. I attached the correct diagram you'd need to use for your application.

  • Maximum Amp Rating of Roadmaster Hy-Power Diode
    The Roadmaster Hy-Power Diode # RM-790 is rated for a maximum of 85 amps. This is for a single diode but is also available in different quantities if you need: - Quantity of 1: Roadmaster Hy-Power Diode # RM-790 - Quantity of 2: Roadmaster Hy-Power Diode # RM-792 - Quantity of 3: Roadmaster Hy-Power Diode # RM-793 - Quantity of 4: Roadmaster Hy-Power Diode # RM-794 I have added links to video reviews for you to check out as well.

  • What is the Voltage and Amperage Rating for Roadmaster Diodes
    Roadmaster diode # RM-790 is rated for a maximum of 24 volts and 85 amps. So you can use it on a 12 or 24 volt system as long as the amperage draw does not exceed 85 amps. At 30 volts that would exceed the rated capacity of the diode and eventually you would have to replace the diode if the voltage was sustained over 24 volts long enough and/or frequent enough.

  • Diode Kit Recommendation for Installing Hopkins Tow Bar Wiring on Vehicle with InvisiBrake
    The # RM-794 would be the correct kit to install the Hopkins Wiring Harness part # HM56007 in your 2012 Ford Focus with the Invisibrake part # RM-8700. I attached a diagram of how it will install as well.

  • Difference Between Roadmaster Hy-Power Diodes # RM-792 and # RM-794
    The only difference between the Roadmaster Hy-Power Diodes # RM-792 and # RM-794 is the quantity of diodes included with the kit. The # RM-792 includes two diodes while the part # RM-792 includes four. Otherwise the diodes themselves are exactly the same. I have attached a short video review below that you can check out as well.

  • Flat Towing Base Plate Kit for 2021 Chevy Blazer with 3.6L Engine
    By twist lock couplers, I'm assuming you're speaking of a flat towing base plate kit. A Saturn vehicle and a Chevy Blazer would use a different base plate kit, so you'll need to get a new kit. As long as your Blazer doesn't have the skid plate, the Roadamaster # RM-523204-5 kit will work great for you. As far as a wiring goes, you can piece together a kit using the # RM-794 diodes, a length of # 16-4B-1 wire long enough to reach the vehicle taillights from the front bumper, a # RM-910030-7...

  • 2000 GMC Safari Van Brake Light Diodes
    It sounds like you want to flat tow a 2000 GMC safari behind an RV, and you need a flat tow wiring kit to operate your tail lights on the Safari. I would recommend the Roadmaster # RM-152-98146-7 Universal wiring kit which 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. If you only want the tail light diodes,...

  • Wiring a Trailer Towed Behind a Motorcycle for Single LED Taillights
    On your motorcycle the taillight circuit is a separate lighting signal, this means that the brake light is on a different circuit than the turn signal. If you were wanting taillights for your trailer with only one light and in an LED configuration you would need to install a taillight converter and then you can install the taillights of your choice. The Hopkins Tail Light Converter # HM48895 is compatible with LED taillights. This converter will hard-wire into the motorcycle wiring and...

  • Recommended Base Plates and Flat Tow System for 2015 Jeep Wrangler
    For your 2015 Jeep Wrangler to use the Tow Defender # RM-4750, you will need the Roadmaster EZ4 Base Plate Kit - Removable Arms # RM-521448-4. This combination will work well with the Roadmaster Nighthawk All Terrain Tow Bar w/ LED Lights # RM-676. Then you will need a wiring kit for your Jeep. I recommend the portions of the Roadmaster wiring kit # RM-15267 that aren't already integrated into your tow bar. These parts are female spade # RM-300115-00, 3 feet wire loom # 459075-1, 30...

  • 2013 Jeep Wrangler Turn Signals Stop Flashing When Being Flat Towed
    The Roadmaster FuseMaster Fuse Bypass # RM76511 is not vehicle-specific so it can work on a Wrangler but I do not believe that would be the solution to your issue. It sounds to me like you are in need of diodes; I looked up the harness you referred to and while it is similar to something like the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267, your harness did not seem to include diodes like the Roadmaster kit.

  • Where Do Diodes Splice In When Installing Diode Wiring In A 2016 Jeep Wrangler JKU I al
    We don't carry Cool Tech products so I can't tell you for sure how their products work. The URL you pasted didn't work so I couldn't find the harness you purchased but I looked over their website and it looks like all of their flat towing harnesses are a plug and play factory connector style wiring harness and wouldn't require diodes. If your harness is different I would need to know the exact part number to take a look at it. Typically diodes like part # RM-794 get installed just before...
