All crimping tools included are the “full cycling” type and
when used as specified in the installation instructions
L-624 covering the TV, CTV and MS series connectors,
will provide reliable crimped wire to contact terminations.
There is a possibility of additional crimping tools other
than those included being available at present or in the
future for this specific application.
The following data includes information pertaining to the
appli
cation tools which have been established for crimping,
inserting, and removing contacts incorporated in the TV, CTV and

Assembly Instructions
WIRE STRIPPING
STRIPPING DIMENSIONS
1. Strip wire to required length. (See Figure at right). When using
hot wire stripping, do not wipe melted insulation material on wire
strands; with mechanical strippers do not cut or nick strands.
2. See Table 1 for proper finished outside wire dimensions.
3. Twist strands together to form a firm bundle.
4. Insert stripped wire into contact applying slight pressure until wire insulation butts
against wire well. Check inspection hole to see that wire strands are visible. If there
are strayed wire strands, entire wire end should be re-twisted.
When wire is stripped and properly installed into contact, the next step is to crimp the
wire inside the contact by using the proper crimping tool.

1. Insert stripped wire into contact crimp pot.
Wire must be visible through inspection hole.
2. Using correct crimp tool and locator, cycle
the tool once to be sure the indentors are open,
insert contact and wire into locator. Squeeze
tool handles firmly and completely to insure a
proper crimp. The tool will not release unless
the crimp indentors in the tool head have been
fully actuated.
3. Release crimped contact and wire from
tool. Be certain the wire is visible through
inspection hole in contact.

Examples of M22520 Series Crimping Tools:
Shown top: tool used for small size 22, 22D
and 22M contacts.
Shown bottom: tool used for size 20, 16 or 12
contacts and has a positioner that can be
dialed for each contact size.
CONTACT INSERTION
1. First remove hardware from the plug
and receptacle and slide the hardware
over wires in proper sequence.
2. Use proper plastic or metal insertion tool
for corresponding contact. (Consult
Insertion Tool table on preceding page).
Slide correct tool (with plastic tool use
colored end) over wire insulation and slide
forward until tool bottoms against rear
contact shoulder.
3. Next align the tool and contact up to
the properly identified cavity at rear of
connector plug. Use firm, even
pressure; do not use excessive
pressure. It is recommended to start at
the center cavity. Contact must be
aligned with grommet hole and not
inserted at an angle. Push forward until
contact is felt to snap into position
within insert.
Plastic tool with contact in proper position.
Note: All plastic tools are double-ended. The colored side is the insertion tool
and the white side is the removal tool.

tool. Repeat operation with remainder of
contacts to be inserted, beginning with

5. After all contacts are inserted,
fill any empty cavities with wire
sealing plugs. (Refer to sealing
plug charts for Series III on page
29, for Series I & II and SJT see
page 30-31.
6. Reassemble plug or receptacle hardware slide forward and tighten using connector pliers. Connector holding tools are recommended while tightening back accessories. When
using strain relief, center wires at bar clamp.
Slide clamp grommet into position and tighten
clamp bar screws. When tightening screws,
pressure should be applied in the same direction that clamp is threaded to rear threads of
connector. When not using clamp grommet,
build up wire bundle with vinyl tape so clamp
bar will maintain pressure on wires.
CAUTION, when inserting or removing contacts, do not
spread or rotate tool tips.
CONTACT REMOVAL
1. Remove hardware from plug or
receptacle and slide hardware back
along wire bundle.
2. Use proper plastic or metal removal tool for corresponding
contact. (Consult Removal Tool
table on page 167). Slide correct
size tool over wire insulation.
3. Insert plastic or metal removal tool into
contact cavity until tool tips enter rear
grommet and come to a positive stop. Hold
tool tip firmly against positive stop on contact shoulder. Grip wire and simultaneously
remove tool and contact. (On occasion, it
may be necessary to remove tool, rotate
90° and reinsert.)
Use white end of plastic tool for
removal of contacts.
