HARNESS CONNECTOR

HARNESS CONNECTOR (SLIDE-LOCKING TYPE)

A new style slide-locking type connector is used on certain systems and components, especially those
related to OBD.

The slide-locking type connectors help prevent incomplete locking and accidental looseness or discon-
nection.

The slide-locking type connectors are disconnected by pushing or pulling the slider. Refer to the figure
below.
CAUTION:

Never pull the harness or wires when disconnecting the connector.

Be careful not to damage the connector support bracket when disconnecting the connector.
