3. From the wire end of the housing, align each 
terminated pin or socket with the appropriate 
contact cavity. Then grasp the wire directly behind 
the contact insulation barrel and push the contact 
with a twisting motion into the contact cavity until 
the contact stops and the housing cone fingers 
engage. See Figure 3, Detail A.

Terminated pin and socket contacts are 

interchangeable between the housings. This or 

keying plugs can be used for additional polarization 

when mating the connectors.

4. After all required contacts and keying plugs have 
been inserted into the housing, move the housing to 
the close position. Grasp the wire end of the housing 
and push it until the second tooth of each latching 
arm engages as shown in Figure 3, Detail B. 

3.2. Inserting Keying Plugs

1. Select an empty contact cavity of the housing to 
be keyed. Ensure that the corresponding contact 
cavity of the mating housing is empty. If it is not, the 
keying plug will not engage.

2. With the housing in the open position (refer to 
Figure 2), insert the keying plug into the wire end of 
the housing. See Figure 4.

If removal of the keying plug is necessary, manually 
or using pliers, grip the keying plug, and pull it from 
the contact cavity using a twisting motion.

3. After all keying plugs have been inserted into the 
housing, move the housing to the closed position. 
Grasp the wire end of the housing and push it until 
the second tooth of each latching arm engages 
(refer to Figure 3).

3.3. Mating Connectors

1. Verify that the contact positions of the mating 
connectors are identical.

2. Align and push the housing into the mating 
connector until it bottoms and the locking latch 
engages with the locking tab. See Figure 5.
