I Just Did This Yesterday
In another thread I asked this question and I posted some info.
Yesterday I completed the job of transferring leather seats from an 01 ZJ to another 01 ZJ. After browsing thru many "clunkers" at my yard, I learned that the seat bolting arrangement (4-2 front of the seat, 2 back) is identical in all the ZJ/WJ models.
The seats that I bought did not have heat but they had all the positions. That's all I wanted.
You will find in the leather seats a wiring harness. There are only 2 wires in each seat that you need to make all those positions operable. In the driver's seat, red is 12V+ and black is ground. In the passenger Red/Light Blue is the 12V+ lead and black is ground.
Routing your power source I leave to you. This job took me less than 1 hour. Good luck! This was one of the simplest and most rewarding mods I have ever made!
