FIRE HAZARD
If shorted to the vehicle frame, high current conductors can cause hazardous sparks resulting in
electrical fires or molten metal.
DO NOT connect this system to vehicle battery until ALL other electrical connections are made and
mounting of all components is complete. Verify that no short circuits exist before connecting to the
positive (+) battery terminal.
Failure to follow this warning can cause a fire and may result in serious injury or death to you or
others.
DRILLING PRECAUTIONS
Before drilling holes, check the area into which you plan to drill to ensure you do not damage vehicle
components while drilling. All drilled holes should be de-burred and all sharp edges should be smoothed.
All wires going through drilled holes should be protected by a grommet or convolute/split-loom tubing.
