58-Pin Automotive Waterproof Connector – 9-2208656-9, Heavy-Duty Plastic Wire Harness Connector

Part number 9-2208656-9 is a 58-pin heavy-duty waterproof automotive connector from TE Connectivity. The TE Connectivity part number format identifies this as a TE-manufactured connector used in commercial truck, agricultural, and industrial vehicle wiring harnesses. 58-pin connectors are used for complex multi-circuit harness interfaces — ECM main connectors, cab-to-chassis connections, and body control module connections where 50+ circuits must pass through a single sealed interface.

Frequently Asked Questions

How do I identify the correct replacement for 9-2208656-9?

Cross-reference 9-2208656-9 in the TE Connectivity catalog (te.com) to verify specifications and compatible contacts. The part number is typically molded into the connector housing. Verify pin count (58), gender (male plug or female receptacle), locking mechanism, and mounting configuration. For ECM connectors, also verify the connector orientation — some ECM connectors have a specific mounting angle that determines which variant is required.

What contacts are compatible with 9-2208656-9?

TE Connectivity connectors use TE-specific contacts. Cross-reference the connector part number in the TE catalog to identify compatible contact part numbers and the required crimp tool. The contact size depends on the specific connector series — verify before ordering replacement contacts.

How do I manage a 58-pin ECM connector repair?

For ECM connector repairs: (1) photograph the connector and all wiring before disassembly; (2) use a scan tool to record all active fault codes before disconnecting; (3) label each wire with its pin number; (4) extract and replace only the damaged terminals; (5) verify terminal seating with a pull-test; (6) install the back cover; (7) reconnect and use a scan tool to verify all circuits are functional and no new fault codes are present.

Typical Applications

• Diesel ECM: Engine Control Module main harness connections on commercial diesel engines
• Commercial trucks: Cab-to-chassis main harness connections on Class 8 trucks
• Agricultural equipment: High pin count ECM harness connections
• Transmission control: Allison and other automatic transmission TCM connections
