Connect a compatible RV and towed vehicle lighting system with the Blue Ox BX88275 Universal EZ Light Wiring Harness. This flat tow wiring harness provides tail light, brake light, and turn signal operation while dinghy towing.
The Blue Ox BX88275 Universal EZ Light Wiring Harness connects the RV electrical system to the towed vehicle’s lighting circuits. It is designed to provide tail lights, turn signals, and brake lights on the towed vehicle while it is being flat towed behind a motorhome.
This universal kit routes a 4-way flat harness to the front grille area of the towed vehicle for connection to the RV. Blue Ox notes that BX88275 is the universal kit, while model-specific EZ Light kits are listed separately in the Blue Ox application guide.
