• 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 # 40376 to test the...

• 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.

• 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.

• Replacement Roadmaster Diode Recommendation
  Part number # RM-794 is for 4 diodes, so while it would work for you a better option would be to order a quantity of 3 of the part # RM-790 as that is a single diode.

• Will Roadmaster Hy-Power Diodes Work With LED Lights Of 2019 Jeep Wrangler
  The Roadmaster Hy-Power Diodes (Qty 4) part # RM-794 will work perfectly with the LED tail lights of your 2019 Jeep JL. If you are planning on flat towing the Jeep you may consider Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit part # RM-15267 which comes with the diodes, a 6-way plug for the front of the Jeep and a coiled cord to connect the Jeep to the motor home for a nice clean installation.

• 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.

• 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.

• 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...

• 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,...

• Do Diodes Need to be Replaced for Roadmaster Wiring Kit # RM-154 on a 2015 Jeep Grand Cherokee
  If you are using the Roadmaster Universal Hy-Power Diode Wiring Kit # RM-154 then I have some steps you can take to see what is wrong. It could very well be the diodes that you are using. Try using your tester on the wiring right before it enters the diodes if you are getting a signal before they enter the diodes but not a signal afterwards then you need to replace the diodes with part # RM-794. Another possibility is that the wiring itself is bad. You can use the Wesbar # W002230...

• 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. What it sounds like is happening is there is electrical...

• Diodes Only for Tow Bar Wiring for a 2012 Ford Fusion
  We have diodes that you can purchase by themselves without the whole kit. Hopkins has a set of 4 diodes, # 48955, that you could use. Roadmaster also has a 4-pack, # RM-794. Or you can get a single diode using # RM-790, or a pair using # RM-792. It looks like your 2012 Ford Fusion would only need 4 diodes for tow bar wiring so one of the 4-packs is your best option if you need all of them.

• Does my Tow Bar Wiring Harness Require the use of Hy-Power Diodes
  Wherever you use the RV to signal the vehicle's factory lights, diodes will be needed to stop the backflow of electricity. If you are using a set of external lights like part # TL21RK then the diodes will not be needed but since you have the wiring harness attached to your factory lights then you will want to use a set of diodes like part # RM-794. I have attached a diode installation help article for you to take a look at as well.

• 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...

• 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...
