The coils/ignitors get triggered from the ECU.
See http://www.teamfc3s.org/info/articles/demystifying.html
There's a two socket, conenctor on the Lead Coil assy. One wire is black/yellow. The other wire is the trigger wire from the ECU.
The CAS makes a signal when it is rotated and sends that voltage signal to the ECU. The ECU uses that signal to operate the coils/ignitors and the duty cycle of the fuel injectors.
Series five wiring diagrams can be had by downloading from here: https://www.rx7club.com/forum/showth...ht=photobucket
Ignore the Trail coils. Just work on the Lead coil assy. Car runs fine without the trail
Make sure the ENGINE fuse in the interior is good or the car won't start.
