Today I went to check my fuses to see if that's the reason my blower motor wasn't working(it wasn't) but while I was down there I noticed something strange. A few of the slots are empty. Some of them I can tell what they are like FOG and DRL(daytime running lamps right?) But some of them I don't know like IGN(ignition maybe) and a few others I can't remember them right now. Anyone know anything about this, should I go buy some fuses? By the way it's a 91 RS.

 

I'd surmise that the IGN that's missing is actually a connector for ignition-switched power. Then of course if you don't have fog lights, there isn't likely to be a fog light fuse.
