This was far easier than the AUDI seat project that we failed at. Please be careful picking seats.
I found 2001 Jeep Grand Cherokee seats with the "premium package"
For what it's worth, I paid $140 for seats, brackets, and working electrical with pig tails (required). I didn't purchase heat control buttons or seatbelt ends. Here's how I installed these into my 2001 Jeep Wrangler TJ.
I had help from a friend who is great with electrical, so here's what we did...
We used a large adjustable wrench and a pvc pipe for leverage to bend the rear brackets on the passenger seat.
We made 2 L brackets for each seat made of 3/16" steel. The bracket bolts into the stock front seat mounting holes, they go forward and bend down behind the brackets of the WJ seats which are vertical.
Here's the drivers side brackets
The seatbelt ends were bolted onto perfect size holes on the base of the new seats. I did a much better job bending the one on the drivers side. Must be careful of the wire that runs through the drivers side one if you want the seatbelt alert light to still work.
On the drivers side seats, we had to remove this extra little piece from the bottoms of each front mount bracket.
We wired from the blue switched power auxiliary that's hidden under the dash. You'd have to find it and pull it out of the sleeve. This wire was split to send power to both seats. Then both were grounded. We only used two wires from the harness, the rest were zipped and taped back. I'm not going to use the heat functionality, due to all the warnings of fires and other issues. I think if I care enough, I will get an aftermarket heater with relays switches and instructions.
Once installed, we cut out some of the plastic molding to fit past the seatbelt retractor.
One issue we had, which resolved itself somehow... We bend the brackets on the back of the drivers seat and seat was pressed to far into the center console. We straightened them out and were trying to size up how we would drill the hole through the floor and it seemed like it was cutting it too close to the edge. Then we noticed that the holes somehow lined up perfectly. So this wasn't an issue anymore.
The rear brackets may need to be played with so the seat will be centered between the console and the door. FWIW, the seats are tight, but mine do fit.
Overall, I was so happy that this went so well. The seats are so plush and comfortable. I have tilt, which is awesome for highway driving. I have electric lumbar support and recline. They look WAY better than stock seats and they're leather. Sun? Don't care right now. Maybe I'll get covers, maybe I wont. Not too concerned for cheap money.
