On my rig I ran a 10 gauge wire from the battery with a presolderd ring to a acc block with 4 taps. This block was mounted with a cover in a accessible location not far from the battery and a factory ground point behind the battery.

From this point have run 4 different devices all using various gauge wire and arrangements. These circuits have direct battery and can be fused or relayed however are not ignition switched so if not turned off battery can fail...

You could run a leg of direct or relay to your cab and switch. Depends on your preference. There is also a Acc tap in your cab under the dash you could go to if you do not want to drill through the firewall.
