Mazda 6 Service Manual: Connectors
Data link connector
- Insert the probe into the terminal when connecting a jumper wire to the data link connector.
Caution
- Inserting a jumper wire probe into the data link connector terminal may damage the terminal.
Disconnecting connectors
- When disconnecting connector, grasp the connectors, not the wires.
- Connectors can be disconnected by pressing or pulling the lock lever as shown.
Locking connector
- When locking connectors, listen for a click indicating they are securely locked.
Inspection
- When a tester is used to inspect for continuity or measuring voltage, insert the tester probe from the wiring harness side.
- Inspect the terminals of waterproof connectors from the connector side since they cannot be accessed from the wiring harness side.
Caution
- To prevent damage to the terminal, wrap a thin wire around the tester probe before inserting into terminal.
Terminals
Inspection
- Pull lightly on individual wires to verify that they are secured in the terminal.
Replacement
- Use the appropriate tools to remove a terminal as shown. When installing a terminal, be sure to insert it until it locks securely.
- Insert a thin piece of metal from the terminal side of the connector and with the terminal locking tab pressed down, pull the terminal out from the connector.
Sensors, Switches, and Relays
- Handle sensors, switches, and relays carefully. Do not drop them or strike them against other objects.
Wiring Harness
Wiring color codes
- Two-color wires are indicated by a two-color code symbol.
- The first letter indicates the base color of the wire and the second the color of the stripe.
Fuse
Replacement
- When replacing a fuse, be sure to replace it with one of the same capacity. If a fuse fails again, the circuit probably has a short and the wiring should be inspected.
- Be sure the negative battery terminal is disconnected before replacing a main fuse.
- When replacing a pullout fuse, use the fuse puller.
Direction of View for Connector

Vehicle-harness-side connector
Direction of view is from the harness side.
* : Part names are shown only when there are multiple connector drawings.
Other
Because vehicle-harness-side connectors, such as the DLC 2, have to be viewed from the terminal side, the direction of view is from the terminal side.
