Instructions:
1. Park the Chevy in a level spot and engage the parking brake. Turn off the engine and allow it to cool down. If you have an electric parking brake, be sure to disable it before proceeding.
2. Chock the wheels of the Chevy to prevent it from rolling. Place a chock behind one of the front tires and one of the rear tires.
3. Jack up the rear of the Chevy until the tires are off the ground. Be sure to use jack stands to support the vehicle.
4. Locate the 7-way electrical connector on your Chevy. It is typically located on the frame near the rear of the vehicle.
5. Connect the trailer brake controller to the 7-way electrical connector. Follow the instructions that came with your trailer brake controller to make sure it is wired properly.
6. Route the wiring for the brake controller to the vehicle's battery. You may need to drill a hole in the firewall to run the wiring through. Use a grommet to seal the hole and prevent water from entering.
7. Connect the wiring to the vehicle's battery. Be sure to use a fuse to protect the wiring.
8. Fill the master cylinder with brake fluid. The master cylinder is typically located under the hood of the vehicle. If the brake fluid is low, add enough fluid
9. Press the brake pedal several times to bleed the air from the brake lines. This will ensure that the brakes work properly.
10. Test the trailer brakes by applying the brake controller while towing a trailer. The trailer brakes should engage smoothly and stop the trailer effectively.
Note: If you are replacing the complete trailer brake setup on your Chevy, it is recommended that you consult a professional mechanic or follow the instructions provided by the manufacturer of the new trailer brake system.
