Cable

You dont need to buy the expensive Yamaha cable to make this work. I have gathered this info to share.
The cable is a simple VAG COM OBDII (16 pins) cable (ISO9141 and KWP2000 transmission protocol) for max $10 on Ebay.
Pin 4 = GND
Pin 16 = 12V
Pin 7 = DATA

Simply connect OBDII cable with 3 wires to 3 pins (male) engine connector or alligator clips

Viewing engine plug:

             [] GND(to 4)

TX(to 7)[] [] 12V(to 16)

When you switch on engine, cable led must light on, if not, invert TX and 12V.
