As long as you put it close to the power source... the battery. It's little use having a good length of wire before a fuse...

Often, the battery will have its own larger fuse though, before all the relays, and as long as the wire from the relay to the battery is large enough, it will blow the battery fuse before glowing red hot in a fault.
