If you choose not to install a remote control to turn the LEDs on and off, change the color, and create lighting effects, you can choose a static LED color by connecting specific LED color wires to negative ground (-). You can splice the LED ground wire or a combination of ground wires to customize the LED output color beyond red, green, or blue.

You must connect all 12 Vdc wiring for the LEDs to a fuse at the power-source end of the cable. You should connect the LED yellow positive (+) power wire to a 12 Vdc power source through an isolator switch or circuit breaker to turn the LEDs on and off. You can use the same isolator or circuit breaker controlling the power supply to your stereo, which allows you to turn the LEDs and the stereo on and off at the same time. The fuse must be installed between the LED cable and the isolator switch or circuit breaker.

You should use 20 AWG (0.5 through .75 mm²) or thicker wire to connect the LEDs to the power source.
