24.4.6 Daisy Chain between Methods A and B
In rare situations where more braids need to be terminated for a connector than three per ring terminal and
a mixture of Methods A and B have been used, it is allowable to daisy chain a maximum of two shields
together from a Method A termination to a Method B (Figure 24-12). All other restrictions and
instructions for the shield termination technique set forth for Method A and B are still applicable.
The maximum length of the combined braids should be approximately 4 inches.

24.4.7 ID Program Pins (Strapping)
The GDU 37X rear connector (J3701) is electrically isolated. For installations using
programming pins, a ground pin must be tied to the connector shell.
ID Program Pins provide a ground reference used by the hardware as a means of configuration for system
identification. The following instructions will illustrate how this ground strapping should be accomplished
with the Jackscrew Backshell:
1. Cut a 4 inch length of 22 AWG insulated wire.
Flat Braid is not permitted for this purpose. Use only insulated wire to avoid inadvertent
ground issues that could occur from exposed conductors.
2. Strip back approximately 0.17 inches of insulation and crimp a contact (item 6, Figure 24-8) to the
4” length of 22 AWG insulated wire. It is the responsibility of the installer to determine the proper
length of insulation to be removed. Wire must be visible in the inspection hole after crimping and
the insulation must be 1/64 – 1/32 inches from the end of the contact as shown in Figure 24-8
.
3. Insert newly crimped pins and wires into the appropriate connector housing location as specified
by the installation wiring diagrams.
4. At the end opposite the pin on the 22 AWG insulated wire strip back 0.2 inches of insulation.
5. Terminate this end via the ring terminals with the other Flat Braid per Steps 8 through 11
(Section 24.4.2
) pertaining to shield termination. If this ground strap is the only wire to terminate,
attach a Ring terminal, #8, insulated, 18-22 AWG (MS25036-149).
