After you've installed the pins into the correct connector location, plug the connector back in and turn the ignition to ON. Press the small white test button on the back of the switch, if one of the LEDs light up you likely have the pins in the correct location. If none of the LEDs light up you should check your wiring.
The DSP5 switch has one nut and two washers, the smooth washer is to remain on the bottom with the tab located in hole #5. If it falls out, turn the switch fully to the left (counter clockwise) and place the washer with the pin into hole #5. Make sure the switch moves exactly 4 positions to the right (clockwise), if not loosen the nut and reposition the pin.
