Yamaha injector management?

[pete-blen]

Anyone know where Yamaha send the signal to the injector from.
ignition , ECU .. theres some fancy pants gizzmo on the end of the cam..

Ecu......................

what 98tls said controlled from inside the ecu, solid state switches controlling the injectors are inside the ecu case. the gizzmo on the end of the cam is the cam position sensor as the injectors work a half crank speed same as the cams so the ecu needs to know the relationship between the crank and cam timing hence the sensor.
