You have two parts to hook up on these buttons, the function side and the led side. To hook up the function follow these steps
- On the red and black micro switch hook up the NO and the COM. The NC will not be used at all.
For the LED you need to use a led harness and connect it to power. The led harness is this one:

To hook these up simply plug one yellow wire and one black wire to the black LED bulb holder on each button. It does not mater what side you connect
what color too. If the bulb does not light simply rotate the bulb 180 degrees in the socket.
