The diodes in this kit convert the 12V signal from your RV to a 9V signal, ensuring that your car's variable voltage tail lights function as intended. 4-Wire harness included for installation. Adapter cord and plug sold separately.

Specs:
This smart diode wiring kit lets you connect your RV's tail, brake, and turn signal lights to your towed car's lighting system so that you'll have the signal lights necessary for flat towing your vehicle.
Because your vehicle has variable voltage tail lights, you cannot use a standard diode wiring kit to get these signal lights. If regular diodes are used on a vehicle that has variable voltage tail lights, the bulbs will light up as though the towed car is braking whenever the tail lights are on. In other words, there will be no difference between the vehicle's brake lights and running lights. This is because variable voltage tail lights use the same wire to power both the brake lights and tail lights. They do this by using a 12-volt signal for brake lights and a 9-volt signal for tail lights.
Smart diodes correctly modulate the 12-volt signal coming from your RV to activate only the intended circuit. The result is that your vehicle's tail lights look and function as intended.
This wiring kit is designed to work with incandescent lights only. If your vehicle has LEDs, you'll need to use the smart diode kit designed for LED tail lights (RO44FR - sold separately) instead.
When installing this kit, you will need to add either a 4-way or 6-way round electrical connector to the front of your vehicle so you can connect to your RV when you're ready to tow. Use one of Roadmaster's coiled cable kits (RM-164-7 or RM-146-7 - sold separately) to get both the connector and the adapter cord needed for fast, easy hookup.
If your RV has separate tail light wiring, wherein the brake and turn signals run on separate wires, you'll need a wiring converter (RM-732 - sold separately) to complete this installation.

The staff at etrailer, talked thru and helped put every part I needed into my cart to install my Blus-Ox tow bar…thx
Locally shop installed. It just works. Boring, and boring is good.
Good advise, Ordered...delivered on time..the best
Smart diodes worked well with my 2023 Chevy Trailblazer. Only two diodes required vs. four that were required in my previous setup on an different vehicle.
Extremely impressed I ordered a wiring harness on a Thursday afternoon expecting it it be delivered on Monday we had changed our travel plans to delay our departure untilTuesday However almost miraculously the part was delivered by 8 am the next morning allowing it to be installed the same day I could not believe it and am extremely impressed at their efficiency
Got here in good shape and on time
This kit worked out great for my 2022 Chevy Equinox. I like how it has separate side plates, which make it easier to attach the main bar. The points where it attaches to the frame seem plenty secure. It is important to watch the videos provided by etrailer as Ryan is very thorough and has good tips for installing. I would also recommend installing additional wiring while having the front end off. Overall, I was able to complete in my driveway. The hardest part was sorting out the wiring for whatever braking and tail lights you decide on. William S helped me pick all the necessary components needed for flat towing behind my Jayco RV. I am looking forward to a summer of camping and having more freedom to explore the area, now having a car.
Very helpful, diligent, and kind. Thank you.
Videos and packaging make this much easier than I thiught
Installation is Easy & Clear. The most challenging part is getting the Fascia Quarter panels to separate from the clips. I found that there is an additional identical screw a little deeper behind the one that is instructed to remove. If both screws are removed - fascia doesn't have to be tugged on and it easily releases itself without breaking any clips. The Safety Cables are not easily routed away from the belt on the passenger side but there are three factory holes in the body that they can be secured to help keep clear from the belt.
What is there to say except it works and works well!
Video explained well how to install. Very happy with install. Works!
Video (2020 Equinox) easy to follow. Passenger side wiring was TIGHT after making the butt connection from the light wiring TO the diode pack. I suggest adding additional wiring to this junction before connecting to the diode pack. Good use of GREEN wiring in kit, pay attention to video.
It was professional installed. It works as describe no issues
