Yeah that’s exactly what I did, ram the wires along the door sill and thru the firewall, and then put a bulkhead hose fitting thru the body plug, and ran air lines to the front and rear bumpers.If you pull back the rug from the elevated front edge (there are push pin thingies holding it) there is a grommet/body plug directly under where your compressor is mounted. You could even just grab something to poke up from underneath if'n you intend to hide that wiring. Used that route from the bed to the dash. Came up through the floor, ran the wire towards the door and used the doorsill covers to run and hide the wiring....Just saying.
All the extra wire will be trimmed to length and better hidden, I just flopped it over for the picture.
