If you still have the gear as part of the front stack rather than a spacer, just drop in a CAS and give it a try. I have no idea if polarity affects CAS pickups, but my home built crank trigger using Chrysler pick ups were affected by polarity. A positive going pulse had a nice flat front on it to trip the SCR but when reversed, the long slow build of the positive side had timing going nuts. Just switching the hookup wires got everything working fine.

Well this could definitely be my problem. My engine was a salvaged Japanese domestic engine from a car which had been in an accident, evidently a front- ender. I pulled apart the engine and everything was fine except for the fact that one of the CAS connector plugs was damaged and there was a small hole in the front cover which I welded up. So, I'm not absolutely sure that in fact I wired them up correctly. Given that there are two sensors with two leads each, and there is a common lead going to both sensors, there are four possible configurations for the wiring. so I have a 25% chance that I have it right.

 Ib a similar note, does anyone know where I might find the proper CAS connectors for the 93 13BREW?

Those are not hall effect sensor. They are called VR or variable reluctance
sensors. You will need a high speed scope to look at the wave form.
Down load the shop manual for the 93.

The shop manual shows only 4 wires.
