Connector Symbols

WARNING: This page is about a different car, the 2005 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.

Most of connector symbols in wiring diagrams are shown from the terminal side.

Connector symbols shown from the terminal side are enclosed by a single line and followed by the direction mark.
Connector symbols shown from the harness side are enclosed by a double line and followed by the direction mark.
Certain systems and components, especially those related to OBD, may use a new style slide-locking type harness connector. For description and how to disconnect, refer to "DESCRIPTION " and "HARNESS CONNECTOR " articles.
