(1) Write the connector hole letters and the type of jumper that is to be removed on the worksheet. The number of contacts on the jumper is the type of jumper (2, 3, 4 or 5 contacts).
(a) If you replace the connector, you must write all the connector hole letters and the type of each jumper that is removed. Write the connector hole letters and the type of each jumper that is to be removed on the worksheet in the figure.

NOTE: This worksheet will be used during the installation and the test procedures.

(2) Remove the jumpers (4) thru (7) as necessary. Hold the connector (3) in your hand and use the ELECTRICAL CONTACTS INSERTION TOOL (8) or equivalent.

NOTE: If it is necessary, cut the jumper wires so that you can easily install the removal tool on to the jumper. Cut the wire 0.250 in. (6.35 mm) from the top of the connector rubber insert.

(3) Remove the sealing plugs (1) as necessary with your fingers or PLIERS - NOSE, SOFT, LONG.
(4) Remove the contacts (2) as necessary, use the ELECTRICAL CONTACTS INSERTION TOOL or equivalent.

NOTE: A small piece of straight wire will help in the removal of the contact.

NOTE: You can install the removed contacts, sealing plugs and jumpers if they were not damaged during the removal.

NOTE: Use the worksheet that you made when you removed the jumpers as an aid to make sure that you put all the jumpers in the correct connector holes.

(a) Hold the connector (3) in your hand.
(b) Push the jumper in to the connector hole until the shoulder of the contact is locked by the collet.

NOTE: When the collet locks the contact, the collet makes a light click sound.

(c) Lightly pull back the jumper to make sure that the contact is locked in the collet. The contact is correctly locked if the jumper does not move rearward.
(d) Remove the insertion tool.
(2) Install the AIPC 73-22-35-80-130 CONTACTS (2) and the AIPC 73-22-35-80-110 SEALING PLUGS (1) in the open connector holes that remain. Use the ELECTRICAL CONTACTS INSERTION TOOL or equivalent.
