HARNESS CONNECTOR (LEVER LOCKING TYPE)

●

Lever locking type harness connectors are used on certain control units and control modules such as
ECM, ABS actuator and electric unit (control unit), etc.

●

Lever locking type harness connectors are also used on super multiple junction (SMJ) connectors.

●

Always confirm the lever is fully locked in place by moving the lever as far as it will go to ensure full con-
nection.

CAUTION:

Always confirm the lever is fully released (loosened) before attempting to disconnect or connect these
connectors to avoid damage to the connector housing or terminals.
