The Jeep TB's are from the staight 6, 4.0l engines in the Cherokee class. I believe that they are from 91-99. Don't quote me on those exact years. I am just giving you info because I see no answers for you yet. Check out this link for install. It was, to me, the best out there:

Some of the years you don't have to take apart the TPS. The electrical hook-up is the same as the DSM.
If you have any questions on my opinions on the mod (pro's and con's) I would be happy to answer in a PM so this thread won't get cluttered.
