These instructions cover inserting pin and socket contacts into the cap and plug housings, mating the
connectors, using test connectors, mounting the cap housing to a panel, and mounting the header to a printed
circuit (pc) board. Reference to instructions for crimping the contacts, installing keying plugs, installing a strain
relief, and extracting the contacts is included. Reference product part numbers are given in Figure 1.
For detailed product description and application requirements, refer to application specification 114-1010.
NOTE
Dimensions in this instruction sheet are in metric units [with U.S. customary units in brackets]. Figures are not drawn to scale.

1. ASSEMBLY
1.1. Inserting Contacts and Keying Plugs (Plug and Cap Housings)
NOTE
Split pin contacts are recommended for use in housings having 6, 9, 12, and 15 circuits to reduce mating force. Grounding pin
contacts (2.54 mm [.100 in.] longer than standard pin contacts) are designed for a mate first, break last (MFBL) grounding
application. Programmable socket contacts are designed to accept 110 series FASTON* receptacle terminals.

1. Ensure that the contacts are crimped to meet the requirements given in 114-1010.
2. Observing the cavity identification numbers on the wire end and the No. 1 cavity identification rib on
the side of the housing, manually insert each contact into a circuit cavity of the housing. After inserting
the terminal into the back of the housing, pull back lightly on the wire of the contact to make sure that
the contact is locked in place. If using keying plugs, leave the circuit cavities to be keyed empty. Refer
to Figure 2.
For contacts crimped to small wire sizes, insert the contact using extraction tool 455830-1 according
to 408-4371 (packaged with the tool).
3. If applicable, insert keying plug(s) according to instruction sheet 408-3320. Refer to Figure 2.
NOTE
Corresponding contact cavity in mating connector must be empty for connectors to engage.
Figure 2
1.2. Strain Relief
Attach the strain relief onto the plug or cap housing according to 408-3320.
1.3. Test Connectors
Touch the 2.13 mm [.084 in.] diameter test probe from the applicable test connector onto the socket contact of
the plug or cap housing. Follow industry-approved testing procedures.
1.4. Panel Mounting (Cap Housings)
1. Cut a panel having the thickness and dimensions given on 114-1010.
2. For the cap housing, insert the cap housing, mating face first, through the panel cutout in the same
direction that the cutout was made until the flexible panel mounting latches snap in place. Refer to
Figure 3.
For the Twist and Lock cap housing, align the pin 1 indicator rib with the short side polarization
opening of the panel, and push the cap housing through the panel. Rotate the cap housing clockwise
until it is firmly seated. In order to prevent foam leakage, a gap between the cap housing flange and
the panel must be no more than the dimension given in Figure 3.
1.5. PC Board Mounting (Headers)
1. Ensure that the pc board material and thickness, layout, and hole configuration meets the
requirements given on the connector customer drawing.
2. If applicable, attach the mounting ears onto the header using 3/8-in. long 6-32 pan head screws
(customer supplied). Refer to Figure 1.
3. Mount the header to the pc board using the soldering requirements given on 114-1010.

1.6. Mating
Ensure that the mating connectors have identical number of circuits and a pin contact mating with a socket
contact. Align the mating faces of the connectors, and push them together until the locking latch fully engages
the locking tab. See Figure 4.

2. CONTACT EXTRACTION
Individual contacts can be removed from the plug or cap housing using extraction tool 318851-1 according to
408-4371 packaged with the tool.
