Well i got my sr20 engine wired up, but missing how to wire the CAS, i bought a disk wheel from wolf that simplifies the whole sistem converting it from 360 ref and 4 sync to a dual pulse 4+1 setup. now here its the deal my sensor requires 12V to operate and the wolf only outputs 5V(as stated in the bottom of page 69 on the manul 4.57).
My question is: Do i supply power from my own 12v source and then connect input trigger ground (pin 27) to the 0V pin on the cas, and input trigger reference (pin 28) to the 360 tooth signal pin (since the 360 tooth where the ref and dual pulse reads ref). Diagram at the bottom.

my other question is: where do i connect the ignition ground to, on S4 leading igniter coils???, it only has 2 wires, i know one its 12v and the other one its the trigger,but not shure where to plug the wolf ground. do i connected to the ground case of the coil??

 

1 Ok get 12Volts from the ignition relay It is only on when the engine is running. These are used in plugin so it shouldn't kill the ECU if it get 12V on the input, You should really ask Wolf first B4U do it!
2 The coil pack is grounded it needs 12V and trigger to ground, the wolf uses a floating earth lead to stop noise getting into the ECU connect the earth in the ignition harness to the coils or atleast close. With out that lead grounded you will have NO spark.

The earth in the ignition harness FROM THE WOLF??
but where in the coils??? to metal case???

 

thats the one to the chassis and coil bracket where you bolt it to the car.
