The rears are a little easier than the fronts since you can lift up the seat bottom and flip down the back to reach all the straps and zipper. A plastic trim tool comes in handy for stretching the neoprene around the child seat anchors (the hardest part of the job).
Just finished a 8 Max White Lux pack. The install was reasonably straightforward w/ aux switch. I wired through a diode to enable a power input from the courtesy light group. Most difficult part was passing wire through fire wall and working in passenger footwell to tap into courtesy power.
