You can put them anywhere you want. If you are comfortable drilling a hole where you want to mount them, then you are golden.
As far as wiring, there is an easy way and a correct way. Easy way is to just run them to the battery, I wouldn't suggest this. The correct way would be to find a non-switched power source and wire it into that. They make fuses that have wire leads on them, that would be easiest, I think. You can just plug the fuse in until you find one that has constant power.
