OP - the fact your tach worked before the swap means something changed. The fact that others have done the same swap and maintain tach function is confusing.

The tach signal on the diagnostic port is for the sensor at the harmonic balancer up front. Kind of a different animal with a different frequency...I think. Correct me if I’m wrong.
