Running wires through hitch boot

[TerraCrawler]

Correction: Title should be "Running wires through the hatch boot"

I am going to be installing my work lights on the back of my rack. Plan is to run wires through hitch boot. I assume people just cut a slice into the area I have marked by the blue box and fish it through? Anything typically done to seal it off after?

Once in the truck, how are wires typically run to the engine. Along the roof/headliner? Or should I go down to the floor and run along the door rockers? I am just looking for any tips that is going to help me run wire from the back to the front of the 4runner.

When you run the wire through the green box in your photo you'll be under the headliner. You can run the wire under the headliner, down the driver side rear pillar and into the area where the lights and jack are located. Then you can run the wire through the tire hump. This will require a fish tape, but it's completely possible to do even without tearing up any plastic panels (as some posts claim). Once you get the wire out of the tire hump, you can run the wire under the door step panel on the edge of the rear door, pass it under the pillar that separates the front/rear door, and then under the plastic step panel until you get to the kick panel under the dash, where your left foot goes. From there you can fish the wire through the grommet into the engine compartment.
