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.
