How to Read System Circuit Diagram

The circuit diagram is designed so the current flows from the top of the diagram (power source) to the bottom of the diagram (ground) as if giving an image of water flow.

1. Fuse No  .
2. Circuit Jumping Information/Direction 
   NOTE: This means "Jump to the information directed with the arrow(s) by their number.

   You will find the other symbol in the direction of the arrow.
4. Terminals-in-One-Connector Mark 
5. Wire Color 
6. Shield Wire 
7. Ground Point 
8. "From" or "To" (With ID Letter (s)) 
9. Specification Variation
