7-Function Connectivity for Comprehensive Towing

1. Running Lights: Powers the trailer's taillights and marker lights.

2. Left Turn Signal / Brake Light

3. Right Turn Signal / Brake Light

4. Electric Brakes: Connects directly to your vehicle's brake controller output.

5. Reverse Lights (or Auxiliary function)

6. 12V Auxiliary Power: Provides power for charging trailer batteries or operating interior lights/accessories.

Effortless Plug-and-Play Installation

Stop cutting and splicing. This custom-designed harness features T-Connectors that plug directly into existing OEM connection points on your vehicle's taillight assembly or body harness. This ensures a factory-grade fit and eliminates the risk of incorrect wiring or damage to your vehicle’s electrical system.
