Ground Terminal (GND)
Make the ground lead as short as possible, leaving enough length to complete the installation
and to allow for any service that may be needed at a later date. To ensure a good ground,
scrape away any paint or undercoating to expose bare metal. Use a "ring" terminal of the proper
gauge and an "outside star washer" (between the chassis and ring terminal) when making your
ground connection. Although you've scraped away the paint to expose bare metal, the outside
star washer will help to "bite into" the chassis for a tight, secure ground.
