Preliminary Instructions
Secure Vehicle
General Instructions
1. Only use OEM specified tools for depinning and crimping connector terminals.
2. When extending or replacing a section of wire, the replacement section of wire should be the same gauge or larger than the original section.
3. Corroded components must be repaired by replacing the affected connector assembly—terminals, seals, and connector body—or with an OEM pigtail assembly designed for the repair.
4. If reusing a connector, always verify new seals are properly installed, all plugs (if applicable) are in place, and all terminals are completely seated and locked.
5. When required apply a small amount of dielectric grease to all connector junctions when reconnecting harnesses and components.
On-Vehicle Soldering and Heat Shrink Precautions
Only perform work on fueled vehicles in well-ventilated facilities designed for the specific vehicle fuel type or in safe spaces outdoors in accordance with all jurisdictional and industry regulations.
Always disconnect negative battery cable when repairing electrical components installed on the vehicle.
1.Verify vehicle is leak-free. Refer to DSM.0037 Leak Check procedure.
2.Refer to ENP-422 Welding and Hot Work Precautions Near CNG and LNG Vehicles to determine whether vehicle must be depressurized or defueled prior to beginning any repair procedure requiring heat, sparks, flame, or other thermal activity.
3.Always cover fuel system plumbing and cylinders with a thermal blanket or other appropriate heat shielding when applying solder or working with a heat gun.
4.Never use a torch or other open flame to apply heat to heat shrink tubing.
Wear approved personal protective equipment (PPE) including safety glasses.
Set emergency brake and place wheel chocks in front of and behind vehicle tires.
When performing service or repairs on any portion of the fuel system, install proper lockout/tagout (LOTO) device(s) and observe all LOTO practices.

Splice Procedure
Step 11
Identify the harness location where the splice connector is to be installed.
Step 21
Use a sewing seam ripper to open harnesses protected by layers of electrical tape, heat shrink material, wire loom, etc. to allow unobstructed access to the wire(s).
Step 31
Use side cutters to cut the suspect/damaged wire harness circuit.
Step 41
Use wire strippers to remove approximately 5/16-in (8 mm) of insulation from the wire end and twist the wire stands together.
When performing multiple splices in a harness, plan to offset splice locations to minimize the possibility of creating a bulge or ridged section in the harness.

Step 81
Slide one end of wire to be repaired into splice sleeve until the wire strands are inserted fully into the metal portion of the sleeve (the wire should bottom out).
Step 91
Squeeze crimping tool until the handles are fully compressed the to fully secure the splice sleeve to the wire. NOTE: When fully compressed, crimping tool will ratchet back to the neutral position. Refer to manufacturer instructions.
Step 101
Gently tug on wire to verify a proper crimp.
Step 111
Repeat Step 3 through Step 10 for other wire end.
Step 121
Step 131
Use a heat gun with a reflector to gently apply heat to splice sleeve starting from the middle and working outwards.
When tubing has shrunk, a small amount of sealant should extend out from the ends of the splice sleeve to insure a complete seal.
Step 141
If wire loom material was removed to access wires, install new wire mesh loom or split corrugated tubing over splice area and secure to harness with electrical tape.
