Correct me if I'm wrong... but on a 13B, the sensor..thingy that goes where a distributer would on a 12A is the crank angle sensor?

If this is correct, can you use this sensor on a 12A?

I want to use it if I can to be able to control my spark through a Megasquirt n' Spark.

 

Yes, it will bolt right in place of the distributor.

 

Hehe, After posting the question, I walked out to the garage and just slipped it in!

Thanks for the answer, though!

 

Don't know about the REWs, but all of the other single dizzys interchange in the front cover.
