Note: Socket contacts should only be used in plug assemblies. Pin contacts should only be used in receptacle assemblies.
Continue to push the contact straight into the connector until contact retention finger (36) locks in place behind retention shoulder (37) on the contact, as indicated by an audible and tactile "click". A slight tug on the wire will confirm the contact is properly locked in place.

When all required contacts have been inserted, complete the assembly by pushing the TPA cover into the fully locked position.
Plug assembly TPA covers may be fully locked by holding the rear of the housing and pushing the TPA cover in until it snaps into the locked position.

Note: To verify that TPA covers are fully locked, apply pressure to both TPA covers. One method to do this would be to install a mating plug to verify that the two assemblies fully engage.
Verify that all contacts are locked into place by giving each wire a slight tug with a force of 4.5 to 8 N (1 to 2 lb).
Insert 2900A011 Seal Plugs (11) into any plug assembly (1) or receptacle assembly (2) circuit without a wire. The seal plug should be pushed in until the flange on the seal plug is firmly against wire seal cover (14) .

Securely lock plug assembly (1) and receptacle assembly (2) together by pushing red CPA (connector position assurance) tab (6) inward, sliding it under connector latch (39) pad, until it "clicks" into position. Once the CPA tab is locked, the connector latch pad cannot be depressed, preventing unintended separation of the plug and receptacle assembly.
