Frequently Asked Questions

How do I identify the correct replacement for 964589-1?

Cross-reference 964589-1 in the TE Connectivity catalog (te.com) to verify specifications. Verify: pin count (16), gender (male plug or female receptacle), locking mechanism, and mounting configuration. The part number is typically molded into the connector housing. For GM, Ford, and other vehicles using TE Connectivity connectors, the OEM parts catalog lists the connector part number for each harness location.

What contacts are compatible with 964589-1?

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 16-pin connector?

Yes. Individual terminal replacement is the most cost-effective repair for 16-pin connectors with 1–3 damaged terminals. Use the appropriate extraction tool for the contact size, remove the damaged terminal, crimp a new terminal onto the wire, and reinsert into the housing until the locking lance clicks. Verify seating with a pull-test before reassembling.

Typical Applications

• Door modules: Window, mirror, lock, and speaker circuit connector repair
• Body control: BCM sub-connector terminal replacement
• Instrument clusters: Cluster sub-harness connector repair
• Automotive repair: OEM connector replacement for damaged 16-pin harness connectors
