Wiring Best Practices
To prevent chafing, run the harness cable through a pass-through hole, using existing holes to pass the
cable through rather than drilling a new one. If drilling is necessary, always check before you drill to verify
you are not drilling into anything unintended behind the drilling surface. Insert a grommet, that is the right
size and type for the hole, into the newly drilled hole to protect the wire and seal with all-weather silicone
as necessary.
Because the device and its wires will usually be exposed to the elements, heat-shrink butt connectors and
ring terminals should be used instead of splicing wires. These connectors are preferred instead of
splicing, even when wires will not be exposed to the elements, as being much better at preventing air and
moisture from reaching wires and causing corrosion.
