Important: When making a splice in an area that may be exposed to moisture use a crimp and seal splice sleeve instead of a Splice Clip. Refer to Splicing Copper Wire Using Splice Sleeves in Wiring Systems.

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 correct size and type of wire.

•	The wire must be of equal or greater size than the original (except fusible link).

•	The wire's insulation must have the same or higher temperature rating.

-	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 (0.313 in) of insulation from each wire to be spliced (a).

5. Select the correct clip to secure the splice. Determine the correct clip size crimp tool and anvil.



6. Overlap the 2 stripped wire ends and hold them between thumb and forefinger.
7. Centre the splice clip (2) over the stripped wires (1) and hold the clip in place.

•	Make sure that the wires extend beyond the clip in each direction.

•	Make sure that no insulation is caught under the clip.




8. Centre the crimp tool over the splice clip and wires.
9. Apply steady pressure until the crimp tool closes.

Make sure that no strands of wire are cut.





Important: Do not extend the crimping tool beyond the edge of the clip when crimping the wire.

10. Crimp the splice on each end (1).



11. Apply 50/50 resin core solder to the opening in the back of the clip. Follow the manufacturer's instructions for the solder equipment.



12. Tape the splice. Roll on enough tape in order to duplicate the thickness of the insulation on the existing wires.
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.
