Original Answer:
The question does not make sense. Circuit diagrams for what?
New Answer:
Circuit diagrams are not hidden at all. They can be found in books, hobby stores, or on the internet. However, you have to know what you are looking for.
Circuit diagrams for devices such as computers, televisions, and other devices should be gotten from the manufacturer.

Besides checking engineering texts for these diagrams, there are a number of places to look line. Planet Analog, Red Circuits, AMS, Industrial Controls, and Circuit Finder all have detailed diagrams of capacitive sensors.
Diagrams that represent circuits without a complete path for current flow cannot have current as drawn. This includes open circuits, where a break exists in the loop, or circuits with components incorrectly connected (like a resistor in series with a gap). Additionally, circuits that include components like diodes oriented to block current flow also cannot have current in them. Any circuit that lacks a closed loop or has a break in the conductive path will not allow current to flow.
Scientists use symbols for diagrams of electrical circuits for a simple reason; to save space. The actuall names of the components would take up immense space on the diagram.
Automotive Wiring Diagram SourcesThere are several sources for professional grade automotive wiring diagrams on the Internet but no real "organized" source for "free" wiring diagrams. Searching with a very specific query, ie: "2004 Chevy silverado wiring diagrams" would be a good place to start.Fee based sites include:Alldata [alldatadiy.com] (black & white circuits)Mitchell Repair [autorepair.net] (black & white circuits)Automotive Hobbyists [ahdol.com] (full-color circuits)See Related LinksSee the Related Links for "Automotive Wiring Diagrams" to the bottom for the answer.
Get yourself a Haynes repair manual for that car. It has a lot of good diagrams in it.
The wiring electrical diagrams for the Mercedes-Benz 190 provide detailed schematics of the vehicle's electrical system, illustrating the connections between various components such as the battery, lights, ignition system, and sensors. These diagrams are essential for troubleshooting electrical issues and understanding the layout of circuits in the car. They can usually be found in the vehicle's service manual or through online automotive resources. Proper interpretation of these diagrams aids in effective repairs and maintenance of the vehicle's electrical systems.
Electronic drafting is the process of illustrating various kinds of circuits and wiring systems. the three most common graphical languages used in the illustration of components in circuits and wiring systems are schematic,block,and pictorial diagrams.
