I finally got a day in a warm garage to install the heated seats my wife got for her Jeep for Christmas.
She got the Check Corp seats from Quadratec:
LUX 201MPR - Check Corporation Seat Heaters for 99-10 Jeep® Wrangler TJ, JK & Unlimited - Quadratec
I had read some posts about installing heated seats in <=2010 JK Wranglers, and folks talked about hog rings holding the seat covers on, but in the 2011, it's only plastic channels.
I decided to take the seats out and also took the back off the base... I doubt you could do the install with the seat still in the Jeep like some folks reported in the <=2010 posts. The 18mm bolts were TIGHT. Luckily I had access to in impact wrench. But previously, I did my rear seat recline mod with just a breaker bar, so I think the front seat could be done with some muscle too.
I was a real PITA to shimmy the heater pads up under the seat bottom, but not as bad for the seat back. It seemed to work best to peel back the sticky backing back a few inches at the end and lay it back down. This made it easier to pull the paper back and out once you have the pad in place. Not a lot of room under the seat cover for your hands and the pad.
Here you can see the back wire come down from the right (seat belt side) and the bottom wire coming through cushion (there's already a hole through the cushion).
Now you basically have to take the whole dash apart to tap into the cigar lighter.
First, pop off the lower panel with the net below the HVAC controls. It pops off from the top and is slotted into the bottom. I used a thin putty knife with masking tape wrapped around it to pop it loose.
Second, pop off the panel below the steering wheel. This one also pops off from the top and is slotted into the bottom. Tilt the steering wheel all the way up for more clearance.
Third, pop out the power window switches. Again, I used the putty knife sliding it into the bottom edge. Then unplug the switches from the harness.
Forth, take out the rubber tray in the upper dash.
Now, remove four 7mm screws. Two on either side of the steering wheel. One in the upper dash tray, and one in the hole where the power window switches were.
Now tilt the steering wheel down, and grab the dash up by the windshield and pull it back. The whole panel will unsnap.
Next grab the HVAC panel and pull it back from the top. It will pop off. Then unplug all the connectors on the back of it.
Lastly, pop off the top of the center console. First, grab the shift knobs and pull them straight off. I found it convenient to sit on the center arm rest since the seats are out. I pulled the 4WD lever back for a better angle.
I forgot to take a pic of the console section, but here's one from another thread.
