WARNING! Wire colors and pin locations vary. Please verify with a digital multi-meter.
Pin 5 is the common for the left set of buttons and pin 12 is the common for the right set of buttons. UP &
+VOL are tied together to pin 13. MODE & PTT are tied together to pin 6. DOWN & -VOL are tied together to
pin 14.
Connect a 47 ohm, 150 ohm and 1k ohm resistor on pin 14, 6 and 13. Connect the three resistors together and
connect to the green wire of the SWI-3. The SWI-3 will know if you are pushing the top, middle or bottom set of
buttons due to the different value resistors on each wire. Connect pin 12 to chassis ground. Connect a 560 ohm
resistor to pin 5 and connect to chassis ground. The SWI-3 will know if you are using the left set of buttons and not
the right set of buttons due to the 560 ohm resistor.
