Description
An LED-bulb diode wiring kit for a towed vehicle — Roadmaster part 152789.
Jeep LED and ParkSense application
Roadmaster 152789 is the specialized flat-towing wiring kit for compatible Jeep models with LED taillights, multiplex wiring and ParkSense proximity sensors. Roadmaster warns that ordinary diodes can energize Jeep electronics while towing on certain ParkSense-equipped vehicles and discharge the battery. Use Roadmaster Fitmaster and installation instructions to confirm the exact year, model, bulb type and equipment; a Jeep model-year listing alone does not establish compatibility.
Kit contents and wiring
- Two Smart Diodes for LED-bulb applications, rated at 85 amps each
- 27-foot, 16-gauge four-wire flat harness running from the towed vehicle's front to its taillights
- Terminals, wire ties, split loom and installation hardware
- Separate motorhome-to-towed-vehicle power cord is not included
The Smart Diodes reduce electrical backfeed and modulate variable-voltage signals so the towed vehicle displays the intended brake, tail and turn functions. Follow the Jeep-specific Roadmaster 152789 wiring procedure rather than the instructions for generic diodes.
- Diodes are included to connect the towed vehicle lighting to the motorhome wiring.
- See the vehicle applications below for model-year fitment.
