Separate vs. Combined Lighting Systems

Combined vs Seperate Lighting System

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 Jeep Grand Cherokee 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.

2023 Jeep Wrangler Unlimited

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



by:
Jeep Wrangler

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

  • Recommended Flat Tow Setup for a 2014 Chevy Captiva Sport
    I can definitely help you out with parts to flat tow your 2014 Chevy Captiva Sport. I really like the Demco setup you were looking at because Demco offers a few kits that include just about everything that you need, plus they have very nice tow bars that will last you a long time which you can use on future vehicles you choose to flat tow. For a base plate kit use part # DM9518218 and the the Demco tow bar I recommend is the Dominator # DM9511008 because it has a 7,500 lb weight capacity...

  • Tow Bar and Flat Tow Parts Needed for Heavy 2020 Ram 3500
    We 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,...

  • Correct Tow Bar Wiring For 2022 Jeep Gladiator With LED Lights & ParkSense
    So a couple things here, as by blind spot indicators I believe you are referring to the ParkSense feature on your 2022 Jeep Gladiator. 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. To avoid this, you'll need a Smart Diode kit from Roadmaster: - Roadmaster Smart Diode 7-Wire to 6-Wire Wiring Kit for Variable Voltage LED Tail Lights # RM63MR The diodes in this kit convert...

  • How To Prevent Battery Drain on 2008 Jeep Liberty While Flat-Towed
    In regards to flat-towing a 2008 Jeep Liberty, the battery must be disconnected to prevent drain per the owner's manual. In order to do this, I recommend using the Roadmaster Battery Disconnect part # RM-766 since it allows for this to be done with the flick of a switch, no tools needed and you can do it from inside the cab. Please note, there are specific steps you'll need to follow for setting up the vehicle to be flat-towed, you can find these starting on page 378 of the owner's manual....
