1. INTRODUCTION
Mass Termination Assembly (MTA) .156 Connector-
Holding Fixtures listed in Figure 1 are designed to hold
.156 MTA connectors and discrete wires in position for
termination. The fixture is used with the MTA
applicator assembly or tooling assembly (also listed in
Figure 1). The fixtures are designed for feed-through
(wires are not cut) or closed end (wires are cut)
applications. The connectors are available with up to
26 contact positions on 3.96 [.156] centerline spacing.
NOTE
i
Dimensions in this instruction sheet are in
millimeters [with inches in brackets]. Figures are for
reference only and are not drawn to scale.
For information on operating the applicator or tooling
assembly, refer to the instruction sheet (indicated in
parenthesis in Figure 1) packaged with the tooling.
Read these instructions and referenced material
thoroughly before using the fixture.
Reasons for reissue of this instruction sheet are
provided in Section 7, REVISION SUMMARY.

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.
4. Attach the fixture to the board using screws,
washers, and nuts, or suitable commercially
available hardware.
5. Place wire roll at a convenient location for lacing
into the fixture.
3. SETUP
Select the connector according to the color code that
matches the wire size as shown in Figure 2.

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.
!
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.
3. Terminate the connector according to 408-4260
(if using applicator assembly) or 408-6701 (if using
tooling assembly).
4. Spread the fixture wire combs apart, and lift the
connector out of 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:
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. 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.
NOTE
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.

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
For detailed inspection requirements, refer to
Application Specification 114-1019.
i
NOTE
2. If applicable, test the connector for continuity
using the post retainer assembly.
The post retainer assembly is only included with
some fixtures. Post Retainer Assembly 310672-1 is
available as an accessory for Fixtures 58009-1,
58009-2, 58010-1, 58010-2, 59846-1, 59847-1,
59847-3, 59848-1, 59848-3, 59849-1, and 59849-3
but cannot be used if the fixture is used with the
tooling assembly (58040-1).
