wher does the cam position sensor get its power from? I'm assuming the ECU but cant find what pin it is looking at a pin out.
 
The power is actually 12v from the MPI relay (red wire). The other wires that go to the ECU pins 21 and 22 are the CAS signals (crank angle and top dead center). These signals are just biased to 5v through a voltage divider inside the ECU.
