NOTE: Unless otherwise specified, the lightbar mounting feet must be
sitting as close to the edge of the roof as possible, in full contact with
the roof and not be hanging off the edge.

Routing your Lightbar Cable(s)
1. To protect the headliner from damage, allow a 5” to 7” distance between roof
and headliner by lowering the headliner before drilling.
WARNING!There may be a roof support member that spans the distance
between the driver’s and passenger’s side. DO NOT DRILL THROUGH
THIS MEMBER! Adjust the location until the hole can be drilled without
contacting this support member.
2. Using a 1” hole saw, drill the cable access hole. Use a round file to smooth
and de-burr the edges than insert a 1” grommet.
3. Insert cable(s) through cable access hole into the vehicle. Use RTV silicone
to weatherproof access hole after the cable(s) are pulled completely into
vehicle. Route the cable(s) following manufacturers recommendations.
WARNING: Many vehicles are now equipped with side curtain and
B-pillar air bags. Alternate routing may be required.
WARNING! All Customer supplied wires that connect to the positive
terminal of the battery must be sized to supply at least 125% of the
maximum operating current and FUSED at the battery to carry that load.
DO NOT USE CIRCUIT BREAKERS WITH THIS PRODUCT!
Control Cable:
Refer to the chart on the next page for wire function and fusing. Apply +12 VDC
to a control wire to activate it’s function. Extend the control wires to a customer
supplied switch box and connect following the switch box instructions.
Power Cable:
1. Open the wire shield lid and route the power cable into the wire shield,
towards the firewall. Do not to pinch or crush any wires.
2. Follow the factory wiring harness through the firewall. If you need to drill a
hole in the firewall, be sure there are no components that could be
damaged. After you drill the hole, insert a grommet to protect the cable.
3. Route the cable along the factory wiring harness to the battery.
4. Install a 30 amp fuse block (customer supplied) on the end of the RED wire
in the power cable. Remove the fuse from the fuse block before connecting
any wires to the battery.
5. Connect the fuse block to the POSITIVE (+) terminal on the battery. Leave
no more than two feet of wire between the fuse block and the battery. The
wire between the fuse block and the battery is “unprotected”, do not allow
this wire to touch any other wires.
6. Connect the BLACK wire to the factory chassis ground.
