1. Set the engine wiring harness to the engine, and connect the connector.

NOTE:

• If the clip is damaged, replace it with a new part.

• Before replacing the clip, put an alignment mark (a) on both engine wiring harness and clip to remove the clip, and then align to the alignment mark (a) to attach a new clip to the engine wiring harness.
