6. Insert newly crimped pins and wires into the appropriate connector housing location as specified by
the installation wiring diagrams.
7. Cut the Flat Braid (item 4) to a length that, with the addition of a ring terminal, will reach one of the
tapped holes of the Jackscrew backshell (item 1) (Figure B-1). An appropriate amount of excess
length without looping should be given to the Flat Braid (item 4) to allow it to freely move with the
wire bundle.
Position the window splice to accommodate a Flat Braid (item 4) length of no
more than 4 inches.
8. Guidelines for terminating the newly cutoff Flat Braid(s) (item 4) with insulated ring terminals
(item 7):
• Each tapped hole on the Jackscrew Backshell (item 1) may accommodate only two ring termi-
nals (item 7).
• It is preferred that only two Flat Braid(s) (item 4) be terminated per ring terminal. Two Flat
Braids per ring terminal will necessitate the use of a Ring terminal, #8, insulated, 14-16 AWG
(MS25036-153).
• If only a single Flat Braid is left or if only a single Flat Braid is needed for this connector a Ring
terminal, #8, insulated, 18-22 AWG (MS25036-149) can accommodate this single Flat Braid.
• If more braids exist for this connector than two per ring terminal, it is permissible to terminate
three braids per ring terminal. This will necessitate the use of a Ring terminal, #8, insulated, 10-
12 AWG (MS25036-156).
9. Repeat steps 2 through 8 as needed for the remaining shielded cables.
10. Terminate the ring terminals to the Jackscrew Backshell (item 1) by placing items on the Pan Head
Screw (item 8) in the following order: Split Washer (item 9), Flat Washer (item 10) first Ring
Terminal, second Ring Terminal (if needed) before finally inserting the screw into the tapped holes on
the Jackscrew Backshell. Do not violate the guidelines presented in Step 8 regarding ring terminals.
11. It is recommended to wrap the cable bundle with Silicone Fusion Tape (item 11) (GPN: 249-00114-00
or a similar version) at the point where the backshell clamp and cast housing will contact the cable
bundle.
12. Place the smooth side of the backshell clamp (item 12) across the cable bundle and secure using the
three screws (item 13). Warning: Placing the grooved side of the clamp across the cable bundle may
risk damage to wires.
13. Attach the cover (item 14) to the backshell (item 1) using the two screws (item 15).
