Video Transcript for Roadmaster Tow Bar Wiring RM-792 Review

Speaker 1: Today we're taking a look at the ROADMASTER Hy-Power diode. Now, this will allow motor homes or RVs to power the lights on the tow vehicle without power feedback. The diodes allow electrical current to flow in one direction. So, that'd be from the motor home to the vehicle or to the car. This prevents any electrical feedback and the damage it may cause to the electrical components.This is available in a variety of quantities, so you can get a one pack, a two pack, three pack, or four pack. All options are available at etrailer.com.

For a one pack, use part number RM-790, for a two pack, use part number RM-792, for a three pack, use part number RM-793 and for a four pack, part number RM-794.The spade connectors allow for easy, trouble free, wiring connections. Also, on the back of the packaging, it has detailed wiring instructions, so that's really going to be helpful. So, when you get these, please do not discard the packaging because it has the nice wiring instructions on the back side.The aluminum heat sync helps prevent over heating. The self stick pad on the back allows for easy and secure mounting. Maximum load is 85 amps per diode and please note that four diodes are required for most applications, one for the left turn and break, one for the right turn and break and then two for the tail lights, one per side.That's going to do it for today's look at the ROADMASTER Hy-Power diode..

Roadmaster Hy-Power Diodes (Qty 2) - RM-792

Average Customer Rating:  4.9 out of 5 stars   (115 Customer Reviews)


- RM-792
by:

I purchase these to set up my toad (CR-V) with the Road master 7 to 6 wiring kit along with the 2 back into 3 wire module to allow for me the use the turn signal lights (Yellow) operate separately from the brake lights so that the toad lights all work as they were set up by the manufacturer. This way also allows you to avoid having to buy the brake light relay if your vehicle brake lights are energized by the mechanical function of your braking system. Your overall cost is relative and as stated all of your lights work instead of the typical stop/tail/turn signal bulb on each side. 655651

  • 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.

  • What is the Maximum Voltage of the Roadmaster Diode RM-792
    I spoke with my contact at RoadMaster and the maximum voltage of the Roadmaster Hy-Power Diode, item # RM-792, is 24 volts. The maximum amperage is 85 amps.

  • Can Diodes be Used to Combine Brake Lights and Turn Signals
    What you need is a converter to take the separate turn and brake light circuits and combine them. You will need converter # RM-732. It will take the separate signals and combine them so on the output side you have a green wire for right turn and brake and a yellow wire for left turn and brake. A diode is just a gate. It cannot discern the difference between the brake signal and the turn signal. So if you were turning left or right and braking at the same time chances are the higher...

  • Tow Bar Wiring System to have Separate Turn Signals and Brake Lights on 2017 Buick Envision
    Legally the dingy lights don't have to have separate brake lights and turn signals but you can certainly wire it up that way if you want. I do not know which lighting system you have but the whole kit for separate dingy lights is # 154-792-118158. If you already have a 4 diode kit then you will just need 2 additional diodes # RM-792 and converter # 118158. I have included a diagram showing how the 6 diode system wires up. If you have something other than a 4 diode kit let me know...

  • Flat Tow Wiring for a 2013 Mini Countryman
    Your 2013 Mini Countryman uses a 3-wire lighting system. That means there is a wire for the turn signals, stop lights, and taillights. You will need to install a diode on each of these circuits to prevent power backfeed. If you take a look at the attached photo/article this will give you a better idea of how to wire them properly. If you need an additional two diodes for the extra wires you can use part # RM-792.

  • Troubleshooting Diodes Not Functioning When Installed on a 2001 Honda CR-V
    Before wiring your 2001 Honda CR-V with diodes, you will need to determine if it has combined tail light wiring or separate tail light wiring. Combined tail light wiring carries the turn and brake signals on the same circuit and one bulb on each side of the vehicle carries the running lights, brake lights, and turn signal functions behind a red lens. On a vehicle with a separate tail light wiring system, the turn signals are on a separate circuit from brake lights, often carried behind...

  • Can One Diode be Used Instead of Two If Tapped Into After a Splice
    Yes, the Roadmaster Diode part # RM-792 or part # RM-690 can be installed after the two reverse light circuits are already spliced together. The diodes are basically just a one way check valve for electricity so as long as you are not exceeding the circuit then you will not have any issues.

  • Wiring 2019 Ram 1500 to be Flat Towed Behind RV
    When wiring up your 2019 Ram 1500 so that it accepts the signal lights from your RV, you will indeed need to probe/test the wiring behind the tail lights for function to ensure you are making the correct connections. The process should not be any different for your truck's LEDs than with standard incandescent bulbs. If you already have a wiring kit and it does not include diodes, these will still need to be added to prevent feedback to the RV. We do have diodes available with part #...

  • 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...

  • Recommended Products to Flat Tow a 2013 Ford F-150 XLT
    To flat tow your 2013 Ford F-150 Supercrew you will need a tow bar, base plate kit, safety cable set, tow bar wiring, a supplemental braking system, and most likely a high-low adapter. The Tow Bar that I recommend using is the Blue Ox Avail # BX7420 which is rated for 10,000 lbs and comes with safety cables. Since it uses telescoping arms it is much easier to hook up to your base plates over some other models. I prefer the Blue Ox Base Plate kits that allow you to remove the arms...

  • Recommended Flat Tow Setup for Blue Ox Tow Bar on 2008 Honda CR-V
    For your 2008 Honda CR-V, you will want to start with the Blue Ox Base Plate Kit - Removable Arms # BX2246 which will be directly compatible with your tow bar. The tow bar you are describing is likely the old alpha or avail model, either of which will work just fine. If you want to determine which model you have, you can find it printed on the driver's side leg under the latch handle according to my contact at Blue Ox. If you don't have the safety chains, you will also want # BX88196....

  • Recommendation For Flat Towing 2009 Jeep Wrangler Behind RV
    Yes, either braking system will work. Both the Blue Ox Patriot, Item # BRK2016, and the Roadmaster InvisiBrake System, Item # RM-8700, are good options. Both will need power connections so you can connect the Patriot II with a 12V Outlet Kit like Item # RM-9332 and the InvisiBrake will connect directly to the battery. Of the two, I recommend the Roadmaster InvisiBrake System, Item # RM-8700, because it is a one-time install and then you are good to go. Because you will need to...

  • Recommendation For Flat Towing 2008 Saturn VUE
    The items needed to tow your 2008 Saturn VUE will include base plates, a tow bar, safety cables, wiring, a braking system, and maybe a high-low hitch adapter. For your 2008 Saturn VUE, I recommend the Roadmaster XL Base Plate Item # 3151-1A because it is designed for your vehicle. It also has twistlock brackets that are virtually invisible and can be removed. The Roadmaster Falcon All Terrain tow bar, Item # RM-522, is a great choice that fits the Roadmaster XL Base Plate. You will...

  • Recommendation For 2002 Saturn VUE And Saturn L Series Base Plates

For flat-towing either vehicle, you will also need a tow bar, safety cables, wiring, a braking system, and maybe a high-low hitch adapter. For a tow bar that works with both base plate kits and vehicles, I recommend the Roadmaster Falcon All Terrain, Non-binding Tow Bar, Item # RM-522. For safety cables, I recommend...

Then for the additional diodes you need beyond what you currently have you will use the Roadmaster Hy-Power Diode - (Qty 1) # RM-790 or package of 2 # RM-792. The prices are on each product summary linked or on the individual product pages.

    Curb weight is what your 2017 GMC Acadia Limited weighs without people or baggage in it while the GVWR (Gross Vehicle Weight Rating) is the max amount of weight that your Acadia can handle (which includes the curb weight). Since the Roadmaster Falcon 2 # RM-520 is rated for 6,000 lbs you have 1,344 lbs that you can put inside your Acadia before you have maxed out the tow bar. Naturally you will want avoid maxing out the weight so that your tow bar isn't straining. I recommend putting...

    I reviewed the 2007 Chevrolet Tahoe owner's manual and it can be flat towed. To flat tow your Tahoe, you will need base plates, a tow bar, safety cables, wiring, a braking system, and maybe a high-low hitch adapter. For your 2007 Chevrolet Tahoe 4x4, I recommend the Roadmaster MX Base Plate Kit, Item # 3154-3, because it is designed for your vehicle. It is built with heavy-duty applications in mind. The front arms are easily removable when not in use. The Roadmaster Nighthawk...

The both are compatible with the non-EcoBoost without Adaptive Cruise Control. The difference between these options is that they install slightly different and the removable draw bars have a different design. The Roadmaster XL # 4408-1 will work great with the Roadmaster Falcon 2 Tow Bar # RM-520 and 6K Coild Safety Cables # RM-643. If...

    For tow bar wiring to activate the tail lights on your 2015 Ford Edge Titanium when flat towing it behind a motor home you have a few options. But since you are using a supplemental braking system I recommend using 6 diodes. First you would need the 4 diode kit, # RM-154, and then 2 additional diodes, # RM-792. You would then wire it up like the picture I have included. This will only work if the motor home also has turn signals that are on a different bulb than the brake lights. If...

  • Can the Blue Ox Base Plate Kit # BX1682 Tow a 2002 Yukon SLT that Weighs Over 5,000 lbs
    The 5,000-lb weight limit restriction that you are reading in the installation notes for the Blue Ox Base Plate Kit # BX1682 says that an adapter cannot be used for vehicles over 5,000 lbs. It also states that you will want to check the weight of your model vehicle as some models exceed the 5,000-lb weight limit that the Blue Ox Kit has. The Kit # BX1682 that you mentioned is a confirmed fit for the 2002 GMC Yukon Denali model only so it will not be compatible with your SLT model. The...

    Wiring the different vehicle systems can be a bit confusing but once you know what wiring system your vehicles have and get the proper instructions, you will be able to wire the vehicles. Your 2007 GMC Envoy most likely has a factory 7-Way connector at the rear of the vehicle which is converted to a 2 wire system so you will need to wire the Honda Fit to work with that system. If your motor home has a trailer connector at the rear, it is most likely converted to a 2 wire system also. You...

    The Tow Ready Vehicle To Vehicle Taillight Converter, # 118158, you have referenced will not be needed since you will be staying with a 3-wire system (separate stop and tail lights)on both of your vehicles. The converter is only needed if you had a 2-wire system (combined stop and tail lights) on the towing vehicle and a 3-wire system on the vehicle being towed. I would recommend using a diode system to wire your vehicle because the diodes will prevent feedback from going from the taillights...

    Yes, the Tow Ready Tail Light Isolating Diode System # TR118821 does work to protect both the electrical on your motorhome and your 2013 Nissan 370z (that you input for your vehicle info). Since your motorhome has combined wiring and your 370z has separate (3-wire system) wiring this means that the brake lights on your 370z will function both as the brake and turn lights (when flat towing). If you would like to retain the separate wiring for when you are flat towing then you would also...

The correct Base Plate Kit for your FJ Cruiser is the Roadmaster XL Base Plate Kit # 1183-1 instead. This will work great with the Roadmaster BlackHawk 2 All Terrain, Non-Binding Tow Bar # RM-422 that you mentioned.
