Separate vs. Combined Lighting Systems
This kit will display on your towed car as a combined lighting system - also known as a 2-wire system. A combined lighting system uses the same light bulb to signal both braking and turning (in other words, the car signals a turn by flashing the brake light, while a separate/3-wire system light up independently of each other. Add a wiring converter (118158 - sold separately) and 2 additional diodes to get a separate lighting system.
Do I Need a Brake Light Relay?
Because your vehicle has a combined lighting system - wherein the brake signals and the turn signals are carried on a single wire - 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.

etrailer was extremely helpful in getting me parts to flat tow our 2023 Jeep Wagoneer. More specifically, Noah took the time to research the required parts, offer technical guidance, and follow up to ensure I was taken care of. Top notch service which was much appreciated.

Needed new wiring and diodes for my 2023 Jeep Rubicon. ETrailer makes it so easy to set up all the wiring for flat towing.

This kit was fairly easy to install on a 2021 Jeep Wrangler. If you use this kit to set up a Roadmaster Nighthawk tow bar you do not need the 7-wire to 6-wire coil connector as the tow bar comes with it. Get a 4 diode wire kit without the coil connector and save money.

Works great, to charge battery of toad you need to change the 12v power from center to match the towed vehicle or wire up towed car to center post 12v

- Does Direct Connect Base Plate Kit for 2021 Chevy Equinox Require CrossbarIf you went with the Direct Connect Roadmaster base plate kit for your 2021 Chevy Equinox with part # RM-523193-5 you would not need the crossbar that you are missing so this would be the easiest solution. The temporary install braking kits like the Blue Ox Patriot part # BLU37TR will install and work great without issue. For lighting the diode kit part # DM9523010-54 is a great choice that comes with everything needed to splice into your taillights.

That just leaves a few items such as the the wiring kit, I suggest the Demco 4-Diode Universal Towed Vehicle Wiring Kit, # DM9523010-54. For your supplemental braking, if you have the Demco SBS Air Force One Supplemental Braking System for Motor Homes with Air Brakes, # SM99243, then you all you need is the Second Vehicle Kit, # SM99209.

If you have one of the other models you'd need a diode kit like the part # DM9523010-54. For your tow vehicle that does not have air brakes the DUO part # SM99251 that you mentioned would be a great option. Our installers prefer this system to all of the other permanent install options because of how well it works and how much easier it...

view full answer... - Comparing Base Plate Kits for a 2019 Ford ExpeditionThe best base plate kit for a 2019 Ford Expedition is the Demco Tabless Base Plate Kit part # DM9519318 because it does not have any sort of cross tube that attaches the two side together unlike the Roadmaster Direct-Connect Base Plate Kit part # RM-524457-5 or Blue Ox Base Plate Kit part # BX2678. The lack of a cross tube is going to limit the amount of modifications that are needed which then reduces install time as well so this is really the best route to take. Furthermore, the Demco...

view full answer... - Tow Bar and Flat Tow Parts Needed for Heavy 2020 Ram 3500We can definitely get you a flat tow set up for your 2020 Ram 3500. These trucks are heavy, but the GVWR you are referring to is the gross weight, which is the max weight it can be when loaded with passengers and cargo. According to my research, a 2020 Ram 3500 has a curb weight (unloaded) of up to just over 7,500 lbs max. So even if you have some cargo in the truck, it is difficult to imagine you will be exceeding the 10,500 lb tow bar option you can use with a 2 inch hitch on your motorhome,...

- Which Tow Bar is Compatible with Roadmaster EZ-5 Base Plates for 2020 Jeep Wrangler Unlimited The Roadmaster part you've referenced with part number 521450-5 is no longer available, but it was an EZ-5 base plate so I recommend using the Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar w/ LED Lights - RV Mount - 8K # RM-676, which comes with safety cables integrated into the setup. This would be compatible with the discontinued 521450-5 base plate you've mentioned or the current model, which is the Roadmaster Direct-Connect Base Plate Kit - Removable Arms # RM-521453-5. If...

If it randomly stopped working then the cause is typically just a loose connection or a bad ground so I would check the connections and make sure there's no damage...

If so, you would not be able to use the Demco # DM9523010-54. The issue is that the brake and running lights will all be the same brightness with standard diodes.
