a. All connectors in the SRS, except the seat position sensor connector and occupant classification ECU connectors, are colored yellow to distinguish them from other connectors. These connectors have special functions, and are specially designed for the SRS. All SRS connectors use durable gold-plated terminals, and are placed in the locations shown on the previous page to ensure high reliability.

1. Terminal Twin-Lock Mechanism

Each connector has a two-piece component consisting of a housing and a spacer. This design allows the terminal to be locked securely by two locking devices (the retainer and the lance) to prevent terminals from coming out.

2. Activation Prevention Mechanism

Each connector contains a short spring plate. When the connector is disconnected, the short spring plate automatically connects the positive (+) terminal and negative (-) terminal of the squib.

3. Half connection prevention mechanism:

If the connector is not completely connected, the connector is disconnected due to the spring operation to the extent that no continuity exists.
