Here are pics I promised of removing the back seat hard cover to install Lumbar Support directly in your seat.
Look Under the seat and remove the 2 Straps. The above image shows one of the straps & you basically just pull it toward the front of the car and unhook them both.
Closer picture of the strap (2 of them total though).
This is the hardshell back of seat cover that is to be removed.
Picture of the 2 straps after unhooked from bottom of seat. To remove the hard cover, there are a few clips holding it in. The way I removed it, was to start at the top & pull out just a bit while pulling upward. Look at the clips in the upcoming picture and you can probably figure out an easier way but notice the bottom part/clips requires you to pull UPWARD.
Hard Cover removed. Now you have access to everything you need. To install Lumbar Support, the bladder will be slide between the metal "bed springs" and the actual cloth looking material. Or if you just want to add more memory form, you can do that as well. Basically the Metal "Bed springs" are just holding everything in place.
This is the back view of the Hard Shell Cover that is removed from the seat. See below for side view of the clips, so you can figure out best how to pull it out and up to remove it.

Bottom Clips in image above.
I hope this is helpful, I spent countless hours searching the internet with no luck, so I just went for it. Hopefully this will save some body the hassle and help them fix their own lumbar issues. Even if you have the factory lumbar, if you feel it's not good enough, you can simply use these instructions to add more foam in the areas that need it.
Once I actually receive the Electric Lumbar kit that I will install, I will share details of where I purchased it, the cost, how to install it, and how well it works.
