NOTE
For the item numbers in the following steps 6-13 please refer to
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). 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.
NOTE
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
terminals (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.
NOTE
Choosing to use this tape is the discretion of the installer.
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).
