4.0 PROCEDURE
A. Connector “As Shipped”
Connector ISL shown in “as shipped” condition (closed). The ISL must be removed and
remain removed until all circuits are loaded.
B. ISL removal procedure
ISL must be removed prior to populating the connector. Insert a small screwdriver (3.0-
4.0mm) into the slot located on the ISL and gently twist the screwdriver to unlock the ISL.
Then remove the ISL completely from the connector housing.

C. Terminal Installation:
With ISL still removed, orient the terminal to the rear of the connector as shown below. Grip
the wire behind the terminal insulation crimp and insert it through the appropriate circuit
opening. If resistance is encountered, retract the terminal and adjust the angle of insertion.
Continue inserting the terminal until it stops and locks up on the lock finger with an audible
click or tactile feedback. Installing a terminal will have low effort. Improper installation of the
terminals with lead to high effort and wire buckle.

E. Detecting a partially installed terminal
The ISL will not insert fully with a partially installed terminal. The ISL should slide smoothly
through the cavities until it contacts the ISL snap in features. If any resistance is encountered,
remove the ISL from the connector and check to ensure all terminals are seated fully, and
then try to reinstall the ISL.

F. Connector Mating
To properly mate the connector, first note and align connector keying and ensure both mating
halves share the same color.
Begin sliding the receptacle connector assembly into the header assembly and press firmly
until you hear an audible click.
If resistance is encountered, confirm the ISL is fully locked and all terminals are fully installed.
A partially installed terminal will not allow the ISL to close.
DO NOT FORCE THE CONNECTOR! DAMAGE TO THE TERMINAL, HEADER AND CONNECTOR ISL WILL OCCUR!

I. Terminal Servicing
For 0.50mm Terminals
With a small thumbtack, gently pry up on the terminal lock finger. Once the lock finger is
released pull on the terminal to remove it from the housing. Connector housing may be
damaged during servicing; inspect the terminal, housing, and lock finger for damage.
Components must be replaced if damaged.
Connector housing can be serviced up to two times, then it must be replaced.
For 1.20mm Terminals
Using Tyco extraction tool 5-1579007-3, insert terminal servicing tool fully into the terminal
servicing cavity like shown below. After confirming that service tool has been inserted fully,
terminal can be removed from the connector.
