I cannot verify this until tomorrow:
The wires you want are the Black / Yellow and Green (left turn signal) and Black / Yellow and Gray (right turn signal); these wires will feed into a pair of connectors in the rear of the bike. That info. is correct and from the schematic. I <believe> those wires are located behind the ECU, inside the black rubber boot at the very rear of the area under the bike's saddle. It looks like this:
Again, I cannot verify the position of these wires until tomorrow but it should be correct and you can test them with a meter or test light anyway.
