13. Additional tape can be applied to the wire if the wire does not belong in a conduit or another harness covering. Use a winding motion in order to
cover the first piece of tape.
Splicing Copper Wire Using Splice Sleeves
Use crimp and seal splice sleeves to form a one-to-one splice on all types of insulation except tefzel and coaxial to form a one-to-one splice. Use tefzel
and coaxial where there is special requirements such as moisture sealing. Follow the instructions below in order to splice copper wire using crimp and
seal splice sleeves.

1. Open the harness.
-
If the harness is taped, remove the tape.
-
To avoid wiring insulation damage, use a sewing ripper in order to cut open the harness.
-
If the harness has a black plastic conduit, pull out the desired wire.
2. Cut the wire.
-
Cut as little wire off the harness as possible.
-
Ensure that each splice is at least 40 mm (1.5 in) away from other splices, harness branches and connectors. This helps prevent moisture from
bridging adjacent splices and causing damage.
3. Select the proper size and type of wire.
-
The wire must be of equal or greater size than the original.
-
The wire's insulation must have the same or higher temperature rating (4).
-
Use general purpose insulation for areas that are not subject to high temperatures.
-
Use a cross-linked polyethylene insulated wire for areas where high temperatures are expected.
IMPORTANT: Use Cross-linked polyethylene wire to replace PVC, but do not replace cross-linked polyethylene with PVC.
Cross-linked polyethylene wire is not fuel resistant. Do not use to replace wire where there is the possibility of fuel contact.
4. Strip the insulation.
-
Select the correct size opening in the wire stripper or work down from the largest size.
-
Strip approximately 7.5 mm (5/16 in) of insulation from each wire to be spliced (1).
5. Select the proper splice sleeve (2) and the required crimp nest tool, refer to the Crimp and Seal Splice Table.
6. Place the nest tool in the J 38125 crimp tool.
7. Place the splice sleeve in the crimp tool nest so that the crimp falls at point 1 on the splice.
8. Close the hand crimper handles slightly in order to hold the splice sleeve firmly in the proper crimp tool nest.
