22-Pin Automotive Waterproof Connector – 2-1823440-3, TE Connectivity Plastic Wire Harness Connector

Part number 2-1823440-3 is a 22-pin waterproof automotive connector from TE Connectivity used in truck, agricultural, and industrial vehicle wiring harnesses. The TE Connectivity part number format (X-XXXXXXX-X) identifies this as a TE-manufactured connector. The 22-pin configuration is used for sub-system connections requiring more circuits than standard 16-pin connectors but fewer than 31-pin connectors: instrument cluster connections, body control module sub-connectors, and specialized control unit connections in commercial vehicles.

Frequently Asked Questions

How do I identify the correct replacement for 2-1823440-3?

Cross-reference 2-1823440-3 in the TE Connectivity catalog (te.com) to verify specifications. Verify: pin count (22), gender (male plug or female receptacle), locking mechanism, and mounting configuration. The part number is typically molded into the connector housing. For commercial vehicles, the vehicle manufacturer’s parts catalog lists the connector part number for each harness location.

What contacts are compatible with 2-1823440-3?

Cross-reference the connector part number in the TE Connectivity catalog to identify compatible contact part numbers. The contact size depends on the specific connector series. Verify before ordering — using incorrect contacts will result in improper seating and potential connector failure.

Can I repair individual terminals in a 22-pin connector?

Yes. Individual terminal replacement is the most cost-effective repair. Use the appropriate extraction tool for the contact size, remove the damaged terminal, crimp a new terminal onto the wire, and reinsert until the locking lance clicks. Verify seating with a pull-test before reinstalling the back cover.

Typical Applications

• Commercial trucks: Instrument cluster and BCM sub-connector repair
• Agricultural equipment: ECM and implement control harness connections
• Construction equipment: Control harness connections on heavy machinery
• Bus & coach: Body control and HVAC harness connections
