Do not install this product or route any wires in the deployment area of your air bag. Equipment
mounted or located in the air bag deployment area will damage or reduce the eectiveness of the
air bag, or become a projectile that could cause serious personal injury or death. Refer to your
vehicle owner’s manual for the air bag deployment area. The User/Installer assumes full
responsibility to determine proper mounting location, based on providing ultimate safety to all
passengers inside the vehicle.
Do not attempt to activate or control this device in a hazardous driving situation.
IMPORTANT: READ CAREFULLY BEFORE ASSEMBLY AND USE.

Proper installation of this product requires the installer to have a good understanding of
automotive electronics, systems, and procedures.
If mounting this product requires drilling holes, the installer MUST be sure that no vehicle
components or other vital parts could be damaged by the drilling process. Check both sides of
the mounting surface before drilling begins. Also de-burr any holes and remove any metal shards
or remnants. Install grommets into all wire passage holes.
If this manual states that this product may be mounted with suction cups, magnets, tape or
Velcro®, clean the mounting surface and dry thoroughly prior to
Manual ID: PIM-00000173-V002
Installation:
CAUTION! When drilling it is absolutely necessary to ensure that no other
components or wiring will be damaged. Always check both sides of the mounting
surface. If damage is likely, select a dierent mounting location.

Using the Included Screws
Machine Screw and Bolt Method (user supplied)
NOTE: This method is very secure but only works if you have access to the back
side of the mounting surface.
Using Self-Tapping Screws (user supplied)
NOTE: This method is most eective when mounting to a metal surface. If
mounting to plastic the screws may loosen over time. Also, a power drill/driver
must be used to install self-tapping screws.
Using Double-Sided Tape (user supplied)
Use a drill bit slightly smaller than the screws and drill out the previously
marked holes.
Reposition mounting bracket over holes and attach with the two screws.
Use a drill bit slightly larger than the machine screw and drill out the two
previously marked holes.
Use a machine screw, two washers, a lock washer, and a nut in each hole to
attach the bracket.
Temporarily attach the bracket to the mounting location with tape.
Use two self-tapping screws to attach the bracket to the mounting surface.
Remove tape.
Position bracket on mounting surface and mark location.
Thoroughly clean the bracket and the mounting surface with water and/or
mild soap.
Attach double-sided tape to the bracket and double check the mounting
location.
Attach the bracket to the mounting surface.
Thread the included nuts a few turns onto the thumb screw/bolt.
Slide one nut/bolt assembly into the channel on the side of the box.
Repeat on the other side with the other nut/bolt assembly.
Position the box in the bracket so that the nuts/bolts drop into each side of the
bracket.
Position switch box and tighten both thumb screw/bolt.

To Ground

To test continuity: With your DMM set to read ohms Ω, probe the negative
battery terminal and the potential grounding location. If the DMM reads less
than .5 ohms you have found a good grounding location.
In the above example, the brown wire would run to the power wire of the 36”
light bar, the orange wire would run to the fog lights, the yellow wire would run
to the oodlights, and the green wire would run to the rock lights.
It is also worth mentioning that the switch box does contain a 20 amp fuse,
however, it would also be a good idea to install a fuse in the wire between each
switch and accessory if they are not already equipped with one.

Attach the red wire(s) directly to positive battery power. The easiest way to do this
is by wiring directly to the battery or the positive post on the fuse box.
Attach the black wire(s) to ground. The best way to do this is by wiring to an
existing ground bolt or stud. If this is not possible, the wire can be attached to a
clean, paint-free metal surface that has continuity to the ground terminal on the
battery.
Run each colored wire to the power wires of the accessories you wish to control.
Attach each accessories ground wire to a suitable ground. See step 2 for
information regarding the selection of an appropriate ground location.
Test your new switch box and enjoy!
#1: Low Amperage Wiring
When the total amp draw from all your accessories is less than 20 amps and no
accessory draws more than 15 amps.
#2: High Amperage Wiring
When the total draw from all your accessories is 20 or more amps or one of the
accessories pulls 15 or more amps.
Here, the total amperage is right at the rated capacity of the switch box. In this
situation, it is likely that the 20 amp fuse would fail on a regular basis.
OR
Here the 44” light bar is operating at 15 amps, right at the maximum rating of the
switches in the box. This is a potentially dangerous situation that will cause a
premature failure of the switch.
In both cases a relay is needed to reduce the amperage load on the box and switches.

A relay is an electromechanical device that allows a large electrical load to be
controlled by a separate, much smaller load.
A relay is composed of two separate electrical circuits. The rst circuit is
composed of a terminal that allows power in from a switch, an electromagnetic
coil, and a terminal to ground the coil. The second circuit is composed of a
terminal connected to battery power, a movable armature, a set of contacts, and
a terminal wired to your accessory.
When low current, controlled by a switch, ows through the coil side of the
relay, the coil is magnetized, the armature is pulled down, the contacts make a
connection, and high current is allowed to ow from the battery to the accesso-
ry.
Once the switch is turned o, current stops owing through the coil, a spring
returns the armature to its original position, and current is cut o to the
accessory.
Reduces load on OEM components.
Larger loads than normal can be controlled by the switch as the switch never
physically interacts with the larger load side of the relay.
Heavy duty switches are not needed since only a small amount of current is
required to energize the relay coil.
It is easier to use the correct gauge wire.
It is easier to control multiple accessories with a single switch.
One of the most common types of relays is the 5-pin Bosch style relay. This is
an example of the pin layout and function of a Bosch Style relay.
In this case, pins 85 and 86 are the low current coil circuit and pins 30 and 87 are
the high current accessory circuit. In this situation we will be ignoring 87a.
A typical Wiring setup would look like this:
Two relays will be needed.
Each relay will be connected to the same ACC power source, ground, and
positive post of battery.
But each relay (Pin 87) will need to be wired to a dierent red wire on the
switch box.

If you want your switch box and accessories to function only when the car/ignition is
on, a relay will need to be placed between the battery and the switch box. You will be
using ACC/ignition power to trigger the relay which will then supply power from the
battery to the switch box.
Find an acceptable location to tap into ACC/ignition power (powered only when
the car/ignition is on).
Using a Bosch style relay, wire:
1.
2.
To correctly wire a Bosh style relay rst begin with steps one and two of the low
amperage wiring procedure.
Then wire the correctly colored wire from the switch box to pin 86 on the relay.
For example, if you want to control a light bar with switch A, you would connect
to brown wire to this terminal.
Connect pin 85 to ground.
Next, wire battery power to pin 30. It is a good idea to put a fuse in this wire.
Now run a wire from pin 87 to your accessory.
Finally, attach your accessories ground wire to any acceptable ground.
The best place to borrow power from is an unused ACC fuse terminal in the fuse
box.
If this is not available, an ACC fuse like the horn, cigarette lighter, or radio fuse
can be piggybacked with a fuse tap.
Pin 86 to ACC power.
Pin 85 to ground.
Pin 87 directly to the red wire on the switch box.
Pin 30 to positive post of battery.
