I finished my Rostra Lumbar Support install. I went with the 250-1453 kit due to the seat warmers that came in the C. Not an overly difficult installation, mostly just time consuming. I figure I have about 4 hours invested, but a lot of that is because I get meticulous about wire management and making things semi-easy to reach/remove. First things first, I removed the negative cable on the battery and let it sit for a few minutes. As I was going to be maneuvering around the seat airbag system, I didn't want it going off. After that, it was time to remove the seats...the bolts are reverse torx (I believe E10 or E11...If forget now). I unplugged all the plugs and pulled the seat out. After that, just removed a few tabs and got to work... I undid the hog rings and opened the seat up a bit....you don't need to open it as much as I did (I figured that out on the second one) and put the bag system in then zip tied it in place so it wouldn't mov After that, close it up and run the air tube...I put a piece of wire loom over it to reduce the chances of it getting sliced in the future by the sharp edges of the seat. Next I installed the pump on the bottom of the seat (zip ties right on). After that I had to cut a spot of the switch...I used the supplied template on a piece of tape and cut it out of the side of the seat. Next step was to put the switch in, connect the wires and button it all up... Next, put the seat back in and make all the connections and run the pump wires... After that (and doing the other side) it's a matter of finding a place to ground them and a way to power them and hooking up the battery. I wired mine into the fuse box in a slot that was only powered while the vehicle is on. If you're not familiar or comfortable with doing this, you can easily use an 'add-a-fuse'. All-in-all, I'm satisfied with the way they work...more importantly though, my wife is now a lot comfortable in the seats. Here's the before and after of the driver's side... Uninflated: Unflated:
