9. Wiring Harness Connectors

Several different types of wire connectors are used to connect the wiring harness to the sensors,
actuators, and components installed on the engine. Table 2 identifies the different types of
connectors and guidelines for disconnecting and connecting the wiring harness. Failure to follow the
guidelines in table 2 for disconnecting and connecting the wiring harness could result in damage to
the connector or the locking feature of the connector.
CAUTION USE CAUTION AROUND THE WIRING HARNESS, SENSORS AND
ACTUATORS. THEY CAN BE EASILY DAMAGED AND CANNOT BE
REPAIRED. IF ONE WIRE BREAKS ON THE WIRING HARNESS, THE
COMPLETE HARNESS WILL NEED TO BE REPLACED.
CAUTION USE CAUTION WHEN DISCONNECTING WIRING HARNESS
CONNECTORS. NEVER PULL ON THE WIRES WHEN DISCONNECTING
WIRING HARNESS CONNECTORS. NEVER USE A KNIFE BLADE OR
SCREWDRIVER TO LIFT A LOCKING TAB. IF NECESSARY, USE A THIN
PIECE OF WOOD OR PLASTIC TO LIFT THE LOCKING TAB.
ANY TIME AN ELECTRICAL CONNECTOR IS DISCONNECTED, INSTALL
A CAP ON THE CONNECTOR TO PREVENT DAMAGE OR
CONTAMINATION FROM FOD, CHEMICALS, OR FLUIDS.
NOTICE: Petrolatum or DC-4 lubricant or equivalent can be applied as necessary to the mating
surfaces of connectors.
