I bought the manual because I'm in the process of pulling and rebuilding the V6 motor from wife's 04 Limited (see other post
http://www.toyota-4runner.org/showth...threadid=25254 for exciting details).
The manual seems to be a combination of the "Wiring Schematics" and the "Diagnostic & Troubleshooting" manuals but it doesn't seem to include the "Engine, Body & Chassis" manual.
The manual doesn't include many pictures as shown in the screenshots on the webiste link that you included. The .pdf is text searchable so you can search for the words. If you are looking for a step by step manual like Chiltens, then this manual will not work. If you are looking for technical information about each module, then this should probably work. I also agree with an earlier poster that this was probably pulled off of the Toyota Tech Info Service (TIS) which I didn't know about at the time I purchased the file.
