Here is a link to the TJ Serivce manuals, if you follow along in the downloads section its pretty easy to navigate to the other things in there. The service manual will tell you everything the owners manual will in greater detail.

log in, go to the downloads tab and click "file downloads"
Aside from service manuals they offer the parts list, build sheets, engine info, axle info, audio and wiring diagrams, theres even winching documents in the misc section. I have everything downloaded and saved in a google drive folder that i can quick access on my phone or tablet.
