General Wiring Guidelines
Making Electrical Connections
Approved Omnitracs
Electrical Connectors
The only Omnitracs-approved electrical connectors are crimp butt splices and crimp ring
terminals. Omnitracs recommends Nylon insulated, seamless butt connectors with
inspection windows. Heat-shrinkable butt connectors are preferred. When butt splicing
multiple wires on one end of a butt splice and a different number of wires on the other end,
step-down butt splices are recommended.
Warning: Not following proper wiring guidelines and using improper crimps and butt
splices may cause intermittent connections and may result in unexpected truck down time
or system failure.
Wire Stripping
1.
Using a wire stripper, strip approximately 1/4" off the end of an insulated wire.
2.
3.
After stripping the wire, verify that the wire is not severed, nicked, or damaged by the
stripping tool. If the wire has been properly stripped, it is ready to be butt spliced. If the
wire has been damaged, restrip the wire.
Butt Splicing
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.
