Question:

I have a 2020 Ranger Lariet. Want to find out exactly what I need to wire it up to be towed. My ranger truck has yellow turn signal lights. I plan to install RVI3 brake system. This cause brake lights to activate anytime brakes are applied from what I understand. I see where you wire up the tail lights using a diode kit. What exact kit do I need? Do I need a brake relay of some sort. When wired up with diode kit does this utilize the same red tail light for brake and turn signal? Does my yellow truck turn signal not work with the wire kit? Will it use my truck brake light as turn signal and brake light instead of using the yellow light for turn signal?

We can get your 2020 Ford Ranger set up with a tow bar wiring system, and instead of a wiring kit with separate diodes, I recommend going with an option from Curt:

- Curt Universal Tail Light Wiring Kit for Towed Vehicles # C63CR

The Curt wiring kit splices into your Ranger's lights with butt connectors already attached to the wires; it also uses integrated diodes to make it easier to install, and will splice directly into both the left and right turn signal lights and the brake lights. Along with the wiring kit, you will also need the brake light relay:

- Roadmaster Brake-Lite Relay Kit for Towed Vehicles # RM-88400

This will allow a supplemental braking system like your RVI3 to prevent your Ranger's brake signal from overriding the turn signal, allowing the braking system to work properly.
