2. DESCRIPTION
Each fixture consists of a one-piece locating plate,
housing support, front wire comb, and rear wire comb.
The polarizing tab is used to properly orient the
applicator or tooling assembly with the fixture.
3. Drill holes in the board for mounting the fixture.
Refer to Figure 4 for recommended board layout. If
using connector assembly for testing, cut a slot for
the post retainer assembly.
3. SETUP
4. Attach the fixture to the board using screws,
washers, and nuts, or suitable commercially
available hardware.
Select the connector according to the color code that
matches the wire size as shown in Figure 2.
5. Place wire roll at a convenient location for lacing
into the fixture.

Then select the connector size according to the
required number of contact positions. Refer to
Figure 1 to make sure that the fixture is compatible
with the connector and method of application. Proceed
as follows:
4. TERMINATION PROCEDURE
Refer to Figure 5, and proceed as follows:
1. Spread the fixture wire combs apart, and insert
the connector, mating end first, into the center of the
receiving track. Make sure that the connector
shoulder is behind the locating plate and the
connector ribs are aligned with the slots in the
wire comb.
CAUTION The connector must be located in the center of the
receiving track. Do NOT place more than two
connectors end to end in the fixture.
!
1. Prepare the cable according to 408-9515. If using
the tooling assembly (58040-1), proceed to Section
4, otherwise continue with the following steps.
2. Lace a wire over the slot in the wire combs that
aligns with the applicable connector contact. Make
sure that the wire is straight, then press the wire into
the slot until it bottoms in the wire combs. Repeat
this step until all wires are positioned.
2. Determine the location on the harness board for
the fixture. Make sure space is provided for lengths
of wire between connectors. Refer to Figure 3.
3. Terminate the connector according to 408-4260
(if using applicator assembly) or 408-6701 (if using
tooling assembly).
NOTE
i
The applicator assembly can be rotated 360°,
however, to avoid unnecessary motion, the fixture
should be positioned so that the least amount of
rotation of the applicator assembly is required.
Harness Board
4. Spread the fixture wire combs apart, and lift the
connector out of the fixture.
5. INSPECTING TERMINATED CONNECTOR
1. Visually inspect the connector to make sure that
there is no damage to the housing or contacts.
Damaged products should not be used.
NOTE
i
For detailed inspection requirements, refer to
Application Specification 114-1019.
2. If applicable, test the connector for continuity
using the post retainer assembly.
