Yea...searching for pdf's come up zilch.Chilton/Haynes also does not release any updates or new manuals until a vehicle is almost or already has gone into the next generation change and then they will do the last generation manual on it.

You can get a OEM one for $129 from Chrysler Tech Authority on USB.

You can also get a subscription to Tech Authority for a few days and download to PDF a lot of what most will need for the job at hand. Downloading everything would require days if not weeks of work and would be very time consuming.
Days of getting bootlegged and "Free" complete PDF copies are fewer and far between because many of the OEM's have been clamping down on those who do it under copyright protection.
Up until about 5 years ago or so, you could find a website or even CD's on Ebay with the factory manuals on PDF.Yea...searching for pdf's come up zilch.
The JL wiring diagrams can be had, somewhere on the Wrangler sister site they are available.Wow, $129 for the usb, and it doesn't include the wiring diagrams. That's probably what I would be looking at the most.
