I prefer the solid switch, but you could use something like

I run a 200 amp continuous relay with a toggle switch into the cab. The trick is to cut the power after the starter. Thats where you get all your power draw. You should never see more then 200 amps running all your other stuff in your truck unless you have a large amp in the truck. That way i can turn the power on and off from in the cab.

I just relooked at what i did and the way these trucks are wired up the starter has a constant hot to it and get a kick from a small wire to the relay in the starter much like old chevys. So in reality the small wire going off the battery going over to the relay is where you can kill the power and it will stop power to everything. One thing i have noticed is with my edge programmer i have to have the key turn on before i can turn the key on other wise it wants to put it back to stock setting. heres some pics hope they help.
This one shows the black wire (yes i know wrong color) going from positive to the relay up by the fan for the cab. This is the relay that controls all the power. It then runs power via the red wire to the other relay (the stock ford relay closer to the battery) where everything grabs its power.
another close up of relay
