There is a solenoid on the firewall that you can pull either hot all the time or keyed power. I pulled off the solenoid and you can run the wire through a hole in the rubber panel on the firewall and then I ran it to a 4 port Blue Sea fuse block mounted on the drivers side kick panel. This panel then runs any accessories I wire in the cab.
