toyota CAS help please

[purple people eater]

i need info on the toyota 3rz-fe, 2.7 litre 4 cylender.
is the CAS the 3 wires coiming from the behind the alternator?
i cannot work out how to define the 3 wires on the crank angle sensor, or how many teeth it has, as it is very internal (middle of the block)

the engine also has a cam sensor, that i am also unable to define how it works, only 2 wires coming from it.

the engine has to run on wasted spark (no distributor) so any help on going about this, with these sensors would be great

thanks guys
