Using this cooling fan/clutch pigtail is easy. First, make sure your vehicle's engine is off and cooled down. Locate the old pigtail near the cooling fan or clutch. Carefully remove the old one by detaching the connectors. Then, connect the new pigtail in the same way. Ensure all connections are tight. When it comes to maintenance, check the connectors regularly for any signs of wear or damage. If you notice frayed wires or loose connections, replace the pigtail as soon as possible. Keep it clean and dry to prevent corrosion. Also, avoid over - pulling the wires when using the vehicle to extend its lifespan.
