Thanks to Griff, figured the pin outs for the 2007 GV.
1. GV 2007, Japanese import into India
2. Unit model details
3. Connector used (X86 motherboard to the front panel USB port connector for any desktop)
4.
Success Contraption
5.
Note - No LOW MED HIGH in this unit.
6.
And the pin out details.
Resistor between the 2 trigger pins is 1.5k as suggested by Griff. Make sure your Connector is sitting properly on the Pins - I ended up wasting a whole day because one of the two rows of the connectors were not inserted on the pins! Does anyone know if someone makes an exact female connector for this port?
