Electrical Connections and Circuits

CAUTION: Do not connect a jumper wire from the power source line to a body ground; this may cause burning or other damage to harnesses or electronic components.

CAUTION WITH ELECTRICAL PARTS

Battery Connection Cautions:

Battery Cable
Before disconnecting connectors or replacing electrical parts, disconnect the negative battery cable.

Connector Caution:

Connectors
Removal of connector. Never pull on the wiring harness when disconnecting connectors.

Connector Release Points Indicated By Arrows:

Connectors can be removed by pressing or pulling the lock lever as shown.

Connector Cautions:

Locking of connector
When locking connectors, make sure to listen for a click that will indicate they are securely locked.

Connector Cautions:

Inspection
When a tester is used to check for continuity or to measure voltage, insert the tester probe from the wire harness side.

Connector Cautions:

Check the terminals of waterproof connectors from the connector side, as they cannot be accessed from the wire harness side.

CAUTION:
- Use fine wire to prevent damage to the terminal.
- Do not damage the terminal when inserting the tester lead.

Connector Cautions:

Terminal Inspection
Pull lightly on individual wires to check that they are secured in the terminal.

Terminal Cautions:

Replacement of terminals
Use the appropriate tools to remove the terminal as shown.
When installing the terminal, be sure to insert it until it locks securely.


Insert a thin piece of metal from the terminal side of the connector, and then, with the terminal locking tab pressed down, pull the terminal out from the connector.


Same as the female type.

Electrical Component Cautions:

Sensors, Switches, and Relays
Handle sensors, switches, and relays carefully. Do not drop them or strike them against other parts.

Fuse Replacement
- When replacing a fuse, be sure to replace it with one of specified capacity. If a fuse again fails after it has been replaced, the circuit probably has a short circuit and the wiring should be checked.

- Be sure the negative battery terminal is disconnected before replacing a main fuse.

Fuse Cautions:

- When replacing a pullout fuse, use the fuse puller supplied in the fuse box cover.
