Instructions for Mounting, Wiring and Programming
IMPORTANT! To ensure proper installation installers are required to have a good understanding of automotive electronic, systems and procedures
for proper installation. When you are drilling 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 wiresto 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 cur-
rent carrying capacity of wires and fuses will be signicantly 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 J128. 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 o 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.
Mounting Jeep Lower Windshield Bracket:
• Identify Driver and Passenger side brackets by lining up the two mounting holes on
the back of the bracket along with the curvature of the bracket to the Jeep.
• Remove the existing hardware located on the Jeep and position the bracket in place.
• Using the existing harware from the Jeep, line up the bracket, and mount to Jeep.
• Mount Circle Carbine to the bracket using the attached I bolt in the adjustable oval
track.
• Power cable can be routed through the circle hole behind the oval track for a cleaner
appearance.
