Instead of providing a wiring diagram (which would be unreliable without knowing your car's specific configuration), I'll outline the process and what you need:
1. Obtain a Wiring Diagram: This is the *most crucial* step. You need a factory wiring diagram specific to your 1980 Camaro Z28. These are available from several sources:
* Online resources: Websites specializing in classic car parts and repair often sell downloadable wiring diagrams. Be sure it's for a 1980 Z28.
* Repair manuals: A Haynes or Chilton repair manual for your year and model will contain a detailed wiring diagram.
* Online forums: Camaro-specific forums (like those on classic car websites) may have members who can offer assistance or even scanned diagrams.
2. Identify the Wires: Once you have the diagram, carefully trace the wires from the wiper switch, the wiper motor, and the related components (fuse, relay, etc.). You'll need to identify the function of each wire. Common functions include:
* Power: Usually a switched 12V source (turns on with the ignition).
* Ground: A connection to the car's chassis for completing the circuit.
* Motor Power: The wire(s) that provide power to the wiper motor.
* Switch signals: Wires that carry signals from the wiper switch to control the motor's speed (low, high, intermittent) and park position.
3. Inspect the Components: Before attempting any wiring, carefully inspect the wiper switch, motor, and the wiring harness for any signs of damage, corrosion, or breakage. Replace any faulty components. Corrosion is a common problem in older cars and can significantly affect electrical function.
4. Test the Components: If possible, test the wiper motor separately to ensure it's functional before attempting to wire it into the car.
5. Careful Wiring: Following the wiring diagram precisely, connect the wires. Use proper crimp connectors and electrical tape for secure connections. Avoid loose connections which can cause intermittent operation or even fires.
6. Test and Adjust: Once the wiring is complete, test the system thoroughly. Make sure all wiper speeds and the park position function correctly. If problems persist, double-check your wiring against the diagram.
Disclaimer: Working with car electrical systems can be dangerous. If you're not comfortable working with electricity, it's best to seek the help of a qualified mechanic. Improper wiring can lead to damage to your car's electrical system or even a fire. Always disconnect the battery's negative terminal before starting any electrical work.
