[Ovmsdev] Ford Focus Electric

I've got a line on a scan gauge for a Ford Focus Electric and a vehicle I can plug it into. I should be able to read some interesting values: SOC as XY.Z%, energy to empty (kWh), battery average volts, battery average temperature, accessory battery volts, odometer, average battery charger input power (kW), charge time remaining. I'd like to capture the CAN traffic while reading the values for analysis later. What's the cheapest way to get data out of the CAN bus? Would this work? http://www.amazon.com/gp/product/B005FEGP7I/ref=ox_sc_sfl_title_1?ie=UTF8&p sc=1 Any suggestions on where to source an OBDII Y cable? Tom
