Aftermarket rev counter. Help needed please

Hi all.
Can I wire the signal wire for an aftermarket revcounter onto one of the wires going to an EFI coil pack. I dont have any other output to use unfortunatly.

Many thanks in advance

You can but depending on which tacho, it could read innacurately, but some have adjustment switches.

On the coilpack it is either of the end ones, the centre one is positive feed, but you want the outer negative switched feeds, either one will do.
