Technical Details and Features

  • Ensures compliance with vehicle safety standards for brake lighting
  • Supports electrical system reliability in Chevrolet and GMC trucks and SUVs

Installation Notes and Tips

Before installation, verify compatibility with your specific Chevrolet or GMC model. Disconnect the vehicle battery to prevent electrical shorts. Use the included mounting bracket to secure the relay firmly in place, ensuring stable electrical connections. Confirm that the male blade terminals align correctly with the vehicle’s wiring harness connectors. After installation, test the brake lights to ensure proper relay operation.
