Yes, it goes between the + and GND wires supplying the ignition coil primaries.
To the best of my knowledge, all Miatas have one. On the 1.6 cars, it's tucked up under the fender lip near the igniter module. Not sure where it is on the '94-'00 engines.
It's not a bad thing to have in place- its primary function is to smooth out the supply ripples caused by the coil primaries switching on and off. Commonly, a very large capacitor or capacitor bank (on the order of 10,000 uf or more) is installed as part of a COP conversion, but even so, there's no harm leaving the stock unit in place.

Leafy, on my COP conversion, I put 4 of these (Nippon Chemi-Con 10000uf 25v 105C Axial Capacitor) between the + and - going to the COPs. Probably overkill, but did help with some lost sync 39's I was seeing on the MS3.
The other picture that I saw of this looked like it was mounted on top of the valve cover toward the right rear.
