  I have worked the 6+1 notches in the balancer, the crank sensor is 0 TDC @ 1 & 4 cyl fire notch and as far as I know the ECM handles de the spark timing (EST) and the module selects 1 & 4 or 2 & 3 firing.

  I think we need:

  2 pins sensor - since the crank sensor provides AC signal both wires should be connected
  1 pin REF
  1 pin EST
  1 Pin BY-PASS (crank)
  1 pin GROUND-sensor shield

  Total 6 pins, what I don't have is a dice to make the correct order
  PS. pin 6 is grounded

    if we are talking 2.2 2.5 dis then this is how it works. 

      uses a 6x ref pulse. 60* notches six of them. then a odd man out 10* btdc. thats notch 7 it is the sinch notch for the module. 

      the moduel hanldes conversion of the crank signal into a hmoginized 2x per revolution signal that the ecm would typically see with a distributor application. the notch sequnce for a .23 2.4 sohc dohc quad series engine is the same but the refernce pulse has been moved and i dont remeber to exact were. 

       either way the module handles the signal conversions and the ecm simply changes the duty cylce on the est control line to handle timing.
