Anyone know if it's possiable to install 2 tach's at the same time? I have a digital bar tach in the instrument panel hooked up to the distributor. I would like to install a digital read out tach in the instrument panel to fill a hole left by a removed oil pressure gauge.

I assume I can just parallel the wire the wire come from the coil but would like to hear if anyone has done this before.

A switch can be installed to have one or the other tach reading. If you want them both to be reading at the same time, it might be possible, but i have never did it.

Should be possible. The wire to the coil is just a signal wire.
