I ran all my wires out the bottom of the cab. I used the old fuel tank well (under seat area) as a terminal point. All dash wires run to or from this point, same with engine wires and lighting. If I ever have a problem, I can go under the seat and diagnose it pretty fast. The few engine wires I have run along the left frame rail then out to the engine. I used all black wires to help hide them. The only trick was to get them under the carpet and up to the dash with out showing, going under the truck was the easy part.
