The fact that the diagram shows two "paths" to the tach module from the pickup is pretty strong evidence that the EGR is just a "pass thru" connection and has no role in signal processing or conditioning. This is further evidence that bypassing the EGR for the tach signal as has been done many times is a good solution not just an "it works" solution. I always suspected this, but never opened the EGR to trace the connections.
