Confused, I need help on different fuel pump wiring methods.

[5.0 Fiend]

Okay, I think I may have just figured it out. I did a search, and the only reason I see for having a relay, is because it hooks the pump in to something called an Inertia switch, which if I am correct, shuts the fuel system off if you are hit hard, correct? Since my car had a mechanical fuel pump before, it would not have an inertia switch, so I could just run the red wire from the pump through an in line fuse, to a power source?
I also have another question yet again, what is the easiest way to run the power wire from the pump to the dash? Through the hatchback area somehow? Through the floorpan? Where is a good place to hook into the ignition circuit instead of a switch? Off of the hot wire going to the ignition coil? The pump has to be powered in the start and run posistion, and the coil hot wire is powered in the start and run posistions right?
