Description
| Number | Item | Description |
|---|---|---|
| 1 | Power supply | This means the power supply of fusible link or fuse. |
| 2 | Fuse | "/" means the fuse. |
| 3 | Current rating of fusible link/fuse | This means the current rating of the fusible link or fuse. |
| 4 | Number of fusible link/fuse | This means the number of fusible link or fuse location. |
| 5 | Fusible link | "X" means the fusible link. |
| 6 | Connector number | Alphabetic characters show to which harness the connector is placed. Numeric characters show the identification number of connectors. |
| 7 | Switch | This shows that continuity exists between terminals 1 and 2 when the switch is in the A position. Continuity exists between terminals 1 and 3 when the switch is in the B position. |
| 8 | Circuit (Wiring) | This means the wiring. |
| 9 | Shielded line | The line enclosed by broken line circle shows shield wire. |
| 10 | Connectors | This means that a transmission line bypasses two connectors or more. |
| 11 | Option abbreviation | This means the vehicle specifications which layouts the circuit between. |
| 12 | Relay | This shows an internal representation of the relay. |
| 13 | Optional splice | The open circle shows that the splice is optional depending on vehicle application. |
| 14 | Splice | The shaded circle "•" means the splice. |
| 15 | System branch | This shows that the circuit is branched to other systems. |
| 16 | Page crossing | This circuit continues to an adjacent article. |
| 17 | Component name | This shows the name of a component. |
| 18 | Terminal number | This means the terminal number of a connector. |
| 19 | Ground (GND) | This shows the ground connection. |
| 20 | Explation of option description | This shows a description of the option abbreviation used on the article. |
Probing from Harness Side
Standard type (not waterproof type) connector should be probed from harness side with "T" pin.
- If the connector has a rear cover such as a ECM connector, remove the rear cover before probing the terminal.
- Do not probe waterproof connector from harness side. Damage to the seal between wire and connector may result.

Connector & Harness
Determine which connectors and wiring harness would affect the electrical system you are inspecting. Gently shake each connector and harness while monitoring the system for the incident you are trying to duplicate. This test may indicate a loose or poor electrical connection.
Hint
Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector terminals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs intermittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean the terminals on related connectors in the system.
