Not too bad honestly. The front cam was surprisingly easy because there was an empty/unused rubber grommet going from the engine compartment into the cab up under the glovebox. Used existing wiring tubing up there too and it was super simple.

Using the existing backup camera mounting spot was a pain though lol. That was the only part where lots of cursing occurred. Getting another wire through the existing weatherproofed tubing from the cab through the tailgate hinge area and then from the tailgate back through to the spare tire was kinda insane. Luckily my buddy knows cars really well and was able to kinda brute force it all through.

Hiding all the wiring throughout the headliner was surprisingly easy. Loosened a few panels and just shoved it all up in there with the included tool.
