APPENDIX E — CONNECTOR PART NUMBERS, TERMINAL PART
NUMBERS, TOOL PART NUMBERS, AND REPAIR INSTRUCTIONS
B. Terminal Removal (refer to Figure E–9, View A)
NOTE: When using remover/inserter tool J 41194, take care not to break the tip of the tool. Lay the wire in
the widest part of the wire slot and work toward the tool tip.
1. Loosen and slide the backshell along the convolute conduit.
2. Remove the convolute conduit from the base of the backshell follower. Peel enough conduit from
the harness to allow working access.
3. Slide the backshell follower clear of the connector housing.
4. Remove as much tape wrap as necessary to allow working access.
5. Fully insert the proper remover/extractor tool into the back of the connector until it releases the
terminal.
6. Pull the terminal, wire, and tool out the back of the connector.
7. If replacing the terminal, cut the wire through the middle of the terminal crimp (this minimizes
wire loss).
C. Terminal Crimping (refer to Figure E–9, View B)
1. Strip approximately 6–8 mm (0.236–0.315 inch) of insulation from the wire.
2. Set the crimping tool wire size to number 18 for the ECD or IPD connector. For the optional DDR
connector, set the wire size to number 12. To set the wire size, remove the retainer pin. Lift and
rotate the indicator until the correct wire number is aligned with the SEL NO. arrow. Reinstall the
retainer pin.
3. Insert the contact end of the terminal into crimping tool J 34182. Adjust the crimping tool depth by
loosening the locking ring until the depth adjusting screw is free and turning the adjusting screw
until the top of the terminal is just above flush with the crimping hole (the crimp jaws will contact
the middle of the terminal barrel). Tighten the lock ring to retain the adjustment.
4. Fully insert the wire into the terminal so that the stripped portion of the wire is in the crimp area. A
small section (0.5–1.0 mm (0.020–0.025 inch)) of wire will be visible above the terminal barrel.
5. Squeeze the crimping tool handle until it releases. The terminal is now crimped onto the wire.
6. Remove the terminal and wire from the crimping tool.
7. Tug on the terminal to ensure the crimp is tight.
8. For the optional DDR connector, apply a one inch long piece of heat shrink tubing over the wire
insulation just behind the terminal. Apply heat to shrink and lock tubing to the insulation.
