Steve,

 

Last night I tried to determine the effects of miswiring a properly functioning CAS to one of my EC2’s

 

Reversing the two CAS signals resulted in no sparks (no coil control signal pulses generated and not one spark seen at any RPM).

 

Disconnecting either or both of the CAS signals resulted in no sparks.

 

Reversing the polarity of either one of the CAS sensors also resulted in no sparks.

 

Reversing the polarity of both CAS sensors resulted in sparks that appeared normal in intensity and timing.  This last condition may be a non-issue or possibly an insidious problem.  Probably only Tracy would know which would be the case.  The sensible thing would be to wire things according to his recommendations, of course.

 

In any case, I could not produce the symptoms you are seeing by miswiring known good components as described.

 

Again, for what it is worth…
