The tach. signal input is from the -ive connector of the coil.
You will also need to tap into a 'live' power source to run the tach
and a power source (e.g. headlight) for the tach's backlight.
I run an aftermarket tach. and rely solely on it whenever I use
the '96 MP PCM on my '97 Dak (with the '96 MP PCM, my dash gauges
are not functional).
Hope this helps.
