Question

like electerical maintenence and repairs

Answer 1

There is no "FREE" site for wiring diagrams. These must come from the manufacturer and they charge dearly for that information. All those who publish the diagrams must pay a copyright fee or they can't publish them.
For that information you can get it several ways - - -
1) Purchase a repair manual for your car. The publisher has paid all of the fees for all of the repair information contained in it.
2) Public Library, in the REFERENCE section, you should be able to locate the information you need from their selection of repair, service and shop manuals. This you usually can gather at no cost. But be careful about photocopying the manuals -- many librarians are very aggressive about protecting the copyrights of the publishers.

Go to the constituents residences in the neighborhood. Look on the Haynes and Chilton manuals. Get their cellphone quantity off of them and contact since its going to be tough to uncover a shop that maintains manuals for the autos you indexed.
