General Wiring and Installation Guidelines
Butt Splicing
Butt Splicing
• Omnitracs recommends Nylon insulated, seamless butt connectors with inspection
windows.
• Heat-shrinkable butt connectors are preferred.
Butt splicing can be done inside and outside the cab or enclosure.

.
Make sure the size of the butt splice is appropriate for the job. A good butt splice has these
characteristics:
• The ends of the bare wires are visible through an inspection window.
• The ends of the wires “butt” up against the stop.
• The wires are not exposed beyond splice shielding.
• Crimping does not sever or damage the wires or insulation.

1.
Insert the stripped wires approximately half way into a butt splice, preferably one with
an inspection window for verifying the wire is in the correct position.
2.
Repeat this process for the wire on the opposite end of the butt splice. Once a proper
butt splice is confirmed, it is important to properly crimp the butt splice to hold the
connection.
