Important: RGB buttons do not contain current limiting resistors. Only connect to a compatible RGB controller. Connecting directly to 5V without the use of current limiting resistors or without using a compatible RGB controller will VOID YOUR WARRANTY.
Connect the included wiring harness by locating the pin with the mark on it. This is where the yellow wire is connected.
After locating the yellow wire, connect the remaining wires as shown.
For advanced users, the wires are connected to the LEDs as follows:
Yellow: +5V
Red: Red GND
Green: Green GND
Blue: Blue GND
