Wire compatible towed vehicle tail lights for flat towing with the Blue Ox BX88334 4-diode wiring kit. This kit adds 50 Ohm resistance to help the diode wiring setup work with vehicles that use multiplex wiring.
The Blue Ox BX88334 wiring kit is designed for flat towing and dinghy towing lighting applications on compatible vehicles with multiplex wiring. It uses a 4-diode wiring setup with added 50 Ohm resistance to help connect the RV lighting signals to the towed vehicle’s tail light circuits.
This kit includes a 26' wiring harness with resistors, 6-amp diode modules, wiring, terminals, couplings, and installation hardware. It is intended for hardwire installation and should be matched carefully to the vehicle lighting system before ordering.
Uses four 6-amp diode modules for towed vehicle light wiring
Includes resistors for compatible multiplex wiring applications
Helps operate tail lights, brake lights, and turn signals while towing
Installs into compatible vehicle tail light wiring circuits
Designed for compatible towed vehicles with multiplex wiring. Confirm the vehicle lighting type, brake/turn signal configuration, diode wiring requirements, resistor requirements, and complete flat towing electrical setup before ordering.
1. Confirm Wiring: Verify that the towed vehicle uses a compatible multiplex lighting system and requires the BX88334 resistor-style diode kit. 2. Remove Tail Lights: Remove the driver-side and passenger-side tail light housings according to the vehicle service procedure. 3. Identify Circuits: Use a 12V continuity tester to identify the brake light, turn signal, tail light, and ground circuits. 4. Install Diodes: Connect the wiring harness, couplings, resistors, and diode modules according to the Blue Ox installation diagram. 5. Route and Test: Route the harness to the front of the vehicle, secure the ground wire, connect to the towing vehicle, and test all lighting functions before travel.
