into the vehicle's surfaces, ensure that the area is free of any electrical wires, vehicle upholstery,
fuel lines, etc. that could be damaged. All wiring passing through drilled holes should use
grommets and silicone sealant to prevent wire or moisture damage when passing through
compartment walls.
WARNING! Larger wires and secure or tight connections will ensure longer service life for your
product. It is highly recommended that soldered connections have heat shrink used to protect
the connection. Special attention should be given to the location and method of splicing wires
to make electrical connections to protect these splices from lost power or connection and
corrosion. Insulation displacement connectors are not to be used. To reduce voltage drop,
minimize the number of splices in the wires. The current carrying capacity of wires and fuses will
be significantly reduced under high ambient temperature (e.g. under the hood). Use SXL type
wire in the engine compartment where higher heat resistance is required according to SAE J-
1128. All wires should be in accordance with the minimum wire size and other recommendations
made by the manufacturer and be protected from hot surfaces and moving parts. Grommets,
cable ties, looms, and other installation hardware should be used to anchor and protect all
wiring. Fuses should be properly sized and located as close to the power take off points as
possible to protect the wiring and device. To protect against short circuits, a fuse is included by
STL for all products. Do NOT use a fuse with a higher amp rating than the initial fuse included.
Do NOT use Circuit Breaks with STL Products. Ground terminations should only be made directly
to the battery.
