Two sources for this. I am told that Fixya is suppose to have this resource. Second is Autozone in their online Webpage at the bottom of the page.

You need to register for free on their site. They give you 12 free lookups. There are both Free and Pay sections at the bottom of the page.

If you look up your individual car, then the Wiring section or Electrical, eventually Diagrams will be displayed. The Diagrams have abbreviations for the wire Color. Y= yellow and so forth.
You can manipulate your Browser for a close-up or try using magnify after you have your first copy and work off of that.

Be careful that you actually have the right car. The vehicle is usually displayed on the wiring diagrams' lower right or left bottom corner.

I can not say much about our sites resources for Diagrams. Perhaps another Expert reading this can tell you more. Sometimes a Web search using the vehicle and "wiring diagrams" may help. There are many Pay sites, you will need to weed out them to get to the free stuff.

Oops! Did not realise it was a supra related site. Anyway my son has a toyota 3c turbo charged engine recently installed in his vehicle. We are trying to locate a wiring diagram for this type of engine. ...

Hi Peter,

You have come to the right place.
I was not real sure which diagrams you are needing for your Supra. I am assuming that you need the diagrams for the engine controls. I have compiled the diagrams for your engine controls into a single PDF file for you to download. You can find it on the FileSonic web site at the following link:

Please note that this is a FREE download. You DO NOT have to purchase a FileSonic membership to get it to download to your computer. If you have a filesonic membership great! If you do not, scroll to the lower right of the page and click the link that says "Slower Download". You will then see a timer running above where you clicked near the center of the page. After the timer has timed out, it will display a captcha code that you must enter to continue with the download. The file will only be available at this address for about 3 days, so be sure and save a copy to your computer for future reference.

Please respond back if you need any furter assistance.

Also, your feedback is very important. Please take a few moments to rate my services through the FixYa web site

Thank you for your patronage,

Dave (dttech)

Hello, Well I see you have waited 4 days for help. The old site should be reachable at I do not know if you can get the same Diagram help on this new site, but Fixya use to have Diagrams for free on the old site.

You can try to do a Web search and narrow the search by typing whether you want a Vacuum diagram, Electrical diagram or Brakeline diagram. Also you will find that most Ford and Mercury Dealers have very helpful Parts counter guys who will print a diagram from any picture they can pull up on their Service computers.

The Parts guys usually like to show off their skills and some can even tell you what frequently goes wrong by the parts they sell and the parts their own mechanics install frequently. So you may get diagnostic help with your Diagram by using them.
