Wiring diagrams, electrical connections and circuit diagrams
Connector designations
How to use indexes (coordinate system)
To quickly find connectors, the following diagrams use a grid similar to a cartographic one:
- 1. Find the number of the desired slot in the list of slots.
- 2. Find the index.
- 3. In the drawing, find the cell of the intersection of the letter (vertically) and numbers (horizontally).
- 4. Look for the connector number in the intersection box.
- 5. Follow the line to the connector (if available).
Index table (coordinates of components on diagrams)
Using the example of the above ABS actuator, below is a way to find this component on the wiring diagram.
- 1. The name of the A-61 connector indicates its location in the engine compartment.
- 2. Wiring diagram 1 (1) - (3) the connector is in column B. Moreover, the connector is displayed in column B on all diagrams 1 (1) - (3).
- 3. On the circuit diagram, the connector is located on diagram C-2 in the square with coordinate B1.
- 4. In the wiring diagram, the connector is located in the W-2 diagram in the square with coordinate B2.
Schematic diagrams
These diagrams show the components of their electrical connections in a simplified form. These circuits allow you to trace current flow paths and find faulty components.
The display of electrical connections on the diagrams differs from the real ones (by car).
Wiring diagrams
Wiring diagrams are used when it is necessary to know the actual location of electrical wiring, pins in connectors, wire colors, etc.
