Page 12-21 shows a Grey/red wire to the coil resistor and condensor or a White/green wire to the power transistor. I don't know which is the input to the ECU, I'm guessing its the Grey/ red one and the White green is the output to run the transistor. You'll need a mutimeter with a Frequency meter(Hz) to check.
