There are a variety of wires and connectors used in automotive wiring. Here is a look at the most common:

1. Wiring harnesses: A wiring harness is a large, organized bundle of wires that runs from the battery to all the other components in the car. A harness usually comes with connectors that match up with the individual wires in the harness, making it easy to connect everything together.If you need more information about automotive wiring supply you may navigate to https://perthpro.com.au/collections/wiring.

2. Connectors: Connectors are tiny pieces of metal that attach one wire to another. They come in many shapes and sizes, and can be male or female (or both). There are several different connectors available for use in automotive wiring, but some of the most common include male cigarette lighter plugs, female RCA plugs, and male 12-volt power connectors.

3. Wire Nuts: Wire Nuts are small screws made out of metal that fit into holes on the ends of wires to hold them together. They come in various sizes, so you can fit them easily into tight spaces. Wire Nuts are also useful for attaching wire leads directly to terminals on an electronic device. 

4. Connector testers: A connector tester is a small tool that you use to test whether a connector is properly installed on a wire. It has a small light and probe that you use to determine whether the electrical connection between the wire and the connector is correct.
