What is purple wire for on starter 1980 camaro?

On a 1980 Camaro, a purple wire related to the starter is highly unlikely. The starter motor itself typically uses heavy-gauge wires for power (positive and negative) and may have a smaller gauge wire for the starter solenoid's control circuit, but these are usually black, red, or a dark color. Purple is not a standard color for starter circuits in GM vehicles of that era.

If you've found a purple wire near the starter, it's almost certainly connected to something *else* in the vicinity. To determine its function, you'll need to:

* Trace the wire: Carefully follow where the wire runs to and from. This will lead you to its source and destination, helping identify its purpose.

* Check a wiring diagram: A wiring diagram specific to your 1980 Camaro's model (specify the engine size and trim level if possible) is crucial. These diagrams show the color codes and the function of each wire. You can often find these online through forums dedicated to classic Camaros or in repair manuals.

* Consult a repair manual: A Haynes or Chilton manual for your year and model Camaro will contain detailed wiring diagrams and information on the starter system.

Without knowing the exact location of the purple wire and having a wiring diagram, it's impossible to definitively say what it does. It's very important to avoid any electrical work if you're unsure; incorrect connections can damage your vehicle's electrical system or even cause a fire.
