Europa-List: Tach Question

[Troy Maynor <wingnut54@charter.net>]

Hi Folks,
Anyone ever hook up the recommended tach that goes with a Rotax 912 in
parallel with one that's part of an engine monitor? My panel was built and
wired a few years ago with the Mitchell tach in addition to an Audio Flight
Avionic engine monitoring system. I am now wiring the engine to firewall and
want to use both. Do I need diodes or something?
