Looking at '93 green book diagrams, I see that the pulse comes right off Power Stage terminal 1, then splits to coil terminal 1 (for spark) and panel terminal 5A-6 for the tach. I can give you point-to-point if needed.

It's basically the same for REX.

So the RPM sender is NOT directly tied to the tach.
