Aren't there:
1. pulse type (piezoelectric)
2. hall- effect (magnet transfer) minimum 2 wires could be 3 i think.
3. blade-interuptor (magnet or light/laser) minimum 3 wires
per the first diagram:
I'm guessing that's a powered Hall and white/black is power in a loop off the ECU. Probably 5-9volts.
NCA/BRN leads to J/C 26 and then to "EG" ground. That could be the signal output.
The second pic shows a red wire. But you have a green wire...
Is that the immobilizer?

The J/C 26 is a ground plane (shield) around the sensor. Well, it's shown like that in the schematic. You also notice in the 2nd pic that a bare wire comes out of the wire bundle and is crimped to the metal housing. I think this too is also a shield wire that only shields that extension wire between harness and sensor, etc.
The 2nd pic is not immobilizer, it is the CAM sensor in it's holder/mount with the extension wire. The extension passes through a rubber grommet in the upper plastic cam gear cover, where it then connects to the harness connector.
