1. Strip wires according to contact size: 3/16" for #20 and 9/32"for
#16 and#12. #20 contacts accommodate AWG wire sizes 20, 22, or
24; #16 accommodates 16, 18 or 20; and #12 accommodates 12 or 14.
2. Insert wire into rear of contact. Wire insulation must butt against
rear of contact. Wire must be visible thru inspection hole.
CONTACT INSERTION
3. Use M22520/1-01 crimp tool with proper crimp locator M22520/
1-02. The color code hand on the contact (red for #20, blue for #16
and yellow for #12) must match the color code of the locator and the
insertion tool throughout the crimping and assembly operations.

COLORED END
FOR INSERTION
4. Insert contact and wire into tool jaws. To crimp, squeeze handles
together fully until ratchet release and allows handles to expand;
otherwise, contact cannot be extracted from tool jaws. Maintain slight
insertion pressure on wire while crimping contact to wire.
1. Remove backshell and put wired contacts thru cable clamp opening.
2. Used colored end of CIET tool for insertion. Place wire into tool at
large opening. To facilitate contact insertion, a 6-in. min. free lenght of
wire is recommended.
3. Slide back tool on wire shile holding thumb against wire at opening.
Wire will slip into tool.
NOTE: Socket contacts should be inserted partially into grommet
by hand before using insertion tool.
4. With tool pressed against shoulder of contact, starting at the center 5. When contact bottoms, a slight click can be heard as tines of metal
cavity, insert wired contact and tool into properly identified cavity at reataining clip snaps into place behind contact shoulder.
rear of plug with firm, even pressure. Do not use excessive pressure.
CONTACT EXTRACTION
6. Withdraw tool from rear of plug. To be sure that contact is locked,
pull back lightly on wire. Then remove tool from wire and proceed with
other contacts.
7. After all contacts are inserted, fill unwired cavities with sealing
plugs (insert head last and leave end protruding for ease of removal),
assemble backshell on rear of connector.
1. Remove backshell and slide back along wires to allow access. To
extract a contact, use white end of CIET tool. Place wire into tool at
large opening. Slide back tool on wire while holding thumb against wire
at opening. Wire will slip into tool.
COMPLETION
BROKEN CIRCLE
BREAK
2. Push tool into rear of plug until it bottoms. At this point, tool
releases tines on retaining clip so that contact can be extracted.
3. While maintaining slight insertion force on tool, firmly hold wire
against serrated shoulder at center of tool and extract both wired
contact and tool from plug.
4. Check face of plug or receptacle for proper contact installation. In
socket inserts with a large number of contact, cavities are identified in
a spiral pattern. A projecting line from the spiral indictates omission of a
letter; a broken circle around a cavity indicates transition between
capitals and lower case and double letters.
Dimensions are shown in inches (millimeters).
