Product Description
The Roadmaster 152789 is a towed-vehicle wiring kit with Smart Diodes made for 2021 and newer Jeeps with LED taillights. It connects the Jeep's own turn, brake and running lights to the motorhome's signals while flat towing, and the diodes prevent current from feeding back into either vehicle's electrical system.
These Jeeps use LED, variable-voltage lighting, where ordinary diodes may not produce the correct light signals. Smart Diodes adjust the voltage so only the intended circuit lights up. The kit includes the two Smart Diodes a vehicle needs, along with a wire harness, ground wire, split loom and zip ties.
Compatibility
- 2021 and newer Jeep models with LED taillights

Pro tipWiring and battery tips
- Protect the car’s wiring. Diodes or a separate bulb kit keep the motorhome’s lighting signal from feeding back into the towed vehicle’s electrical system.
- Watch the battery. Some vehicles drain their battery when flat towed; the owner’s manual will say whether you need a charge line or battery disconnect.
