How to Install an LED Rocker Switch
In many cases, auto accessories like driving lights or rear window defoggers, require a power source, so you will need to install a power switch to turn the accessory on and off. Many people prefer installing LED rocker switches for these applications, so when the accessory is turned on the switch lights up, which verifies the item is on.

Crimp the terminals, using the wire crimpers, to each of the wires. Make sure that the terminal ends match the switch terminal. Normally the switch ends are male, so you will need the female ends for the wires.
With the ground wire you will need to locate a good ground, and attach the other end of the ground wire to the source. You can test the ground with a test light. -

Tips & Warnings
When locating a solid ground, it has been my experience to locate a bolt as a source to avoid drilling more holes.
Make sure to disconnect the battery before performing these steps to avoid shorts.
