run the power wire from the battery across the drivers side fender well. put a fuse there close to the battery. continue the wire through the firewall, where you'll find a big hole with a rubber plug about where a clutch pedal rod would be. turn it behind the drivers side kick panel, along the door trough. if its a regular cab, keep on going to behind the B pillar and come under the drivers seat from the rear. i don't know about extended cabs.
