Thanks Rich, It seems maybe that some tachs or subaru MY will work just by hooking it up to the ecu, but so far I've seen more that do need some modification.

I would imagine to make it work that you could just splice into two of the igniter wires going to the coil packs (1&3 or 2&4), and use a diode in each line so you're not shorting anything.
