now yes, of course it deals with the airbag. One of the guys in our club found out that if that fuse is blown, it also cuts off the fuel. What else does it do?

NA or NB, the 1994 NA has a totally different system than the 90-93???
90-93: Miata receives power from 4 circuits. I believe the main power is being provided via the Injector fuse (in the main fuse block under the hood). This circuit is "always on". This circuit also supplies power via an airbag fuse (also on the main fuse block) that charges the backup power module (actually a large capacitor) located under the steering column. This source is also "always on". The module also receives power via the Wiper Fuse and the Airbag fuse located in the fuse box under the dash on the drivers side. These inputs apparently enable the controller circuits as they are on only when the key is in the "on" position.
