You are correct: There is a pickup in the flywheel. I've seen it while I was replacing my rear crankshaft seal. Many cars are missing the small metal plate that has the wire and pickup sensor on it that goes to the diagnostic plug. I actually still had mine. The possible purpose of this pickup other than measuring RPM's by means besides the ignition eludes me. I'm sure a vendor like Don Steger (who worked at the factory) could shed more light on this.
