- Mounting Bracket Installation: Securely attach the provided mounting brackets to the vehicle's chassis at the designated points. Ensure all bolts are tightened to the manufacturer's specifications.
- Running Board Attachment: Mount the running boards onto the installed brackets. Verify that they are level and properly aligned with the vehicle's body.
- Wiring Connection: Connect the wiring harness to the running board motors and the vehicle's electrical system. This typically involves connecting to door sensors and a power source. Ensure all electrical connections are secure and properly insulated.
- Control Module Integration: Install and connect the control module as per the specific wiring diagram provided with the product.

6. Operation
The Deployable Electric Running Boards operate automatically based on your vehicle's door status:
- Deployment: When a vehicle door is opened, the corresponding running board will automatically deploy within approximately 1-2 seconds.
- Retraction: After all vehicle doors are closed, the running boards will retract automatically after a 3-second delay. This delay allows occupants sufficient time to exit or enter the vehicle before the boards retract.

- Inspection: Periodically check all mounting hardware for tightness. Inspect the electrical wiring for any signs of fraying, cuts, or corrosion.
- Lubrication: If recommended by the manufacturer (refer to specific product documentation if available), apply a suitable lubricant to moving parts of the deployment mechanism to ensure smooth operation.
