I am about to order a stinger CAS setup. I am a bit confused on the wiring. This is the first ms3x I have built. I have in the past built and used several MS2 units and just gone with the basic TFI. This time around I wanted to try MS3x and be sequential with COP. I have read the documentation on the CAS and it recommends with "full sized" megasquirts to use the VR circuit. So my question is, when wiring the sensor am I using the VR input on the main connector, which would be pin24? Or do I use the expansion harness VR cam circuit pin 32? I plan to run sequential using LS coils. Based on what i read the CAS will allow me to do full sequnetial

Primary position input always on main board.

awesome thank you. So nothing connects to the cam sensor input? How does it get full sequential without both inputs?

One wheel at cam speed with a singularity (missing tooth) completely defines engine position.
