Alldatadiy.com and Eautorepair.net are the two best shop manuals—period!

Which one should YOU choose?
If you’re tracking down a wiring issue, Eautorepair.net is the better choice. Eautorepair.net redraws factory wiring diagrams in color and includes the component, splice and ground locations right in their diagrams. That saves a lot of time because you don’t have to refer back to the component locator or circuit locations. Alldatadiy.com, on the other hand, uses the factory diagrams. So you have to refer to the factory legends to learn the identification symbols and then refer back to circuit diagrams to find the splice and ground locations.
However, Alldatadiy.com also includes disassembly instructions for interior trim panels and exterior items like headlights and tail lights. If you need to dig into your doors, dash or console, Alldatadiy.com is the better choice because Eautorepair.net doesn’t any interior or exterior trim or body part removal.
