Wiring Instructions
All standard lightbar models are designed for 12VDC negative ground vehicles
only. Reverse polarity will cause serious damage to the lightbar and/or vehicle.
Contact the automotive dealer if there are any doubts about the polarity of your vehicle.
Mounting Instructions
Please review the separate Mounting Bracket manual that
is also enclosed with your bar for mounting instructions.
If the wire supplied is too short, Star recommends direct wiring to the terminal block on
the inside of the lightbar, rather than making connections to the end of the wire that is
supplied. This lightbar is designed so that no wire connectors are needed and only a few
common tools are necessary in order to do this. Direct wiring allows the wire connections
to the lightbar to be made in a clean and dry environment, avoiding any problems that may
arise due to weathering on external connections. There is also an increase in voltage loss
with the addition of each connection. Wiring directly inside the lightbar reduces the number
of connections. However, making connections to the wires already provided is an
acceptable alternative, as long as these connections are good electrical connections and
are resistant from weathering effects. For direct wiring into the lightbar, follow the
instructions listed below.
Direct Wiring Guide
PLEASE NOTE: If you are using the existing 15-foot cable supplied with the lightbar,
you may skip to the Electrical Connections section on page 4.
1. Determine the number of wires that you will need to run. The standard harness used in
these lightbars has 16 conductors, plus a drain wire and a foil shield. Your lightbar may
not need all of the wires. Please note which functions your bar has, then review the Wire
Harness Usage Table on page 1 to determine which wires you will need to connect. The
drain wire and foil shield in our standard harness are optional (but recommended) and
are only necessary if you are experiencing RFI problems.
2. Locate the end of the lightbar with the wire harness attached to it. The black terminal
blocks that you will be making your wire connections at, should also be located at the
same end.
3. Remove the dome lens at this end of the lightbar:
Step A: Loosen the 4 screws securing each dome.
Step B: Lift the dome off of the base exposing the
interior components, or the metal plate
covering the interior components (some
models). If you have no metal plate, skip to
Step 4.
Step C: If your lightbar has a metal plate covering
the components, remove all of the screws
holding the plate on. The number of screws
may vary depending upon the layout of your
lightbar.
Step D: Lift the plate off the lightbar exposing the
interior components.
4. When all work is completed, reinstall the plate and
dome, taking care that the gasket is properly aligned.
