distributor?

why?

unless they did things really really really weird in that engine, the speed sensor is in the tranny... and the rev sensor should be in the tranny too... the dizzy has a crank/cam angle sensor that tells the ECU when to fire the coil and injectors.
As far as I was aware, the rev sensor for the tranny is totally separate of that.
I understood it to be that the engine and ecu and the tranny and TCU are totally seperate and the units talk to each other, instead of sharing sensors.
