INTRODUCTION
The Extreme Off-Road Harness can be used to wire any non-street legal vehicle.
Its 10 circuits and 4 relays will provide power to all critical and accessory components
associated with your vehicle. Unlike other chassis harnesses provided by Painless, this
harness only contains power Inputs and Outputs to and from the fuse block. With this
harness fitting such a wide range of vehicles, these instructions will be general
installation procedures. Referring to a factory wiring schematic of your vehicle will aid in
connecting factory charging and ignition systems and/or connecting to factory switches.
For aftermarket components, following the manufacturer’s instructions will be helpful in
connecting the Painless harness to their specific product.
CONTENTS OF THE PAINLESS WIRE HARNESS KIT
Refer to the Contents Figure (below) to take inventory. See that you have
everything you’re intended to have in this kit. If you find that anything is missing or
damaged, please contact the dealer where you obtained the kit or Painless
Performance at (800) 423-9696.
The Painless Wire Harness Kit should contain the following:
 Wire Harness, with Fuse Block and relays installed
 1 small parts bag containing Maxi Fuse components and terminals
 1 large parts bag containing heat shrink, a junction block, 3 circuit
breakers, zip ties, relays, and a fuse label
 1 parts box containing miscellaneous ring terminals, terminals, fuses,
screws, nuts and washers.
 2 rolled wires (1 charge wire, 1 ignition switch wire)
CONTENT FIGURE- All of the parts in the Painless kit

SMALL PARTS
The bagged parts, as well as the parts box, should provide you with
everything you need in order to properly install the Painless Extreme Off-Road Harness.
The smaller bag containing the large Maxi Fuse contains all the necessary
parts to properly install an in-line fuse between the Alternator and the vehicle’s Battery.
The ring terminals found in this bag will cover a wide range of wire diameters to help
connect all wires your individual installation may require to be connected to the Maxi
Fuse. For additional information on the Maxi Fuse and proper installation refer to page
8.
The larger bag contains circuit breakers for the relays, spare relays, and a
junction block to allow power distribution from the battery and maxi fuse to the fuse
block and circuit breakers. This bag also contains a fuse label for fuse identification, zip
ties, a rubber alternator boot, and heat shrink.
The parts box contains an assortment of fuses and terminals. Mounting
hardware for the junction block and circuit breakers are also located in the parts box.
TOOLS NEEDED
In addition to your regular hand tools, you will need, at least, the following tools:




Crimping Tools*
Wire Stripper
Test Light or Volt Meter
Small (10 amp or less) Battery Charger**
*We recommend that you use a quality crimper to avoid over crimping.
** see TESTING THE SYSTEM located on page 18.
FUSE BLOCK MOUNTING
Fuse Block mounting begins by locating all the necessary parts in the Painless kit
needed for proper Fuse Block Mounting. These parts are:



Fuse Block Mounting Bracket
4 Large Philips Head Screws
2 of the ½” Self Tapping Screws
Begin by finding a suitable location to mount the fuse block. The location of the
Fuse Block must be easy to access, yet out of the way during operation of the vehicle.
Suitable locations for the fuse block can generally be found under the dash or on the
firewall.
The Fuse Block supplied with the Extreme Off-Road harness has a weather proof
seal; however, avoid mounting the Fuse Block where it may become in direct constant
6
contact with water or in a position which could be submerged in water during operation
of the vehicle.
Begin by installing the Fuse Block onto the Mounting bracket. The Fuse Block will
slide into the bracket causing the legs to “wrap” around the Fuse block. Refer to the
photo below and on the next page.
Using the 4 Philips head screws, mount the fuse block to the mounting bracket.
The Fuse Block cover can be mounted to the bracket by utilizing one of the Fuse Block
Mounting Holes. Some my find it easier to cut the tab from the fuse block cover
altogether to allow more room when the cover is removed.
Note: Applying a small amount of a silicone based lubricant on the red seal of the Fuse
Block will aid in getting the cover off at a later time after installation.
If you do not wish to use the mounting bracket, and would like to do a through
panel fuse block installation, a template has been provided for you on page 20.
7
Using 2 of the ½” self tapping screws and the holes pre-drilled at the top of the
Fuse Block mounting bracket secure the bracket to the vehicle.
MAXI FUSE
CAUTION: DISCONNECT THE POWER FROM YOUR VEHICLE BY REMOVING
THE NEGATIVE OR POSITIVE BATTERY CABLE FROM THE BATTERY. THE
BATTERY IS NOT TO BE CONNECTED UNTILL THE PAINLESS HARNESS HAS
BEEN INSTALLED AND TESTED.
Begin by locating the MAXI FUSE component bag in the parts kit. These
components are: a MAXI FUSE Base & Cover, a self-tapping mounting screw, the 100
AMP MAXI FUSE, and several different size ring terminals.
 Using the mounting screw, mount the fuse base as close to the battery, or
battery power source, as possible. This power source can be the Battery
itself or the B+ at the Starter Solenoid.
 Actual connections made to the Maxi Fuse will differ according to your
specific application requirements; refer to the CIRCUIT BREAKERS AND
JUNCTION BLOCK illustration, page 16, for the proper connection of the
Maxi Fuse.
 Install the MAXI FUSE into the BASE, and the COVER over the MAXI
FUSE assembly. Before doing so, make certain that the Positive or
Negative Battery Cable is not connected. Harness failure will result.
8
ROUTING
Try to follow these basic guidelines during your install.
Routing Guidelines
 Route the harness away from sharp edges, exhaust pipes, and hood, door, and
windshield hinges.
 Inside edges provide protection from hazards and also provide places for tie
wraps, clips and other support.
 Plan where harness supports will be located. Allow enough slack at places where
movement could occur (body to frame, frame to engine, etc.). Use a support
about every 12 inches.
 At wire ends, don’t depend on the terminals to support the harness. The weight
of the harness could cause terminals to disconnect or copper wire strands to
break.
Wires should be bundled into groups. Use nylon ties, poly split loom, Power
Braid, or tape. Exposed wires of the engine compartment and wires running to the rear
of the vehicle may need some sort of wiring loom or covering. This is especially true for
vehicles that spend time on off-road trails and/or have their four wheel drive capabilities
tested frequently.
FUSE BLOCK
The following section contains information
about the Fuse Inputs, Fuse Outputs, Relay
wiring, and the color coordination found on the
Painless Harness. All wires going to and from the
fuse block are printed with their function and Fuse
or Relay number. The printed descriptions are
indicated in the text and images of these
instructions as bold and in “quotations”
(example: “FUSE 6 OUTPUT”). With this being a
“universal” style harness and with an infinite
amount of configurations this harness can wire,
there will be no specific instructions on connecting
each wire. It will be up to you, the installer, to
determine were to connect each wire. The only
instruction Painless can give is the type of
connection each wire needs and/or the function of
each wire.
9
Fuse Inputs
The Fuse Input wires are
solid color wires and are color
coded to the Fuse Output wires.
The 3 Fuse input wires are:
 PINK- ”FUSE 1-3 INPUT”
 ORANGE- “FUSE 4-6 INPUT”
 RED- “FUSE 7-10 INPUT”
The power source these Input
wires are connected to will
determine if the Fuse Outputs will
be switched 12v or battery constant.
The splicing to connect each Fuse
Input to the Fuse Block, seen to the
left, comes pre-installed.
The illustration below shows how to create switched 12 volt power. The drawing
shows all wires associated with Fuses 7-10. Fuses 1-3 and/or Fuses 4-6 could also be
used in this manner if more or less switched 12 volt sources are required with your
application. The illustration also does not show the use of the junction block, refer to the
CIRCUIT BREAKERS and JUNCTION BLOCK drawing on page 16. The “BATTERY
B+ TO IGNITION SWITCH” wire seen in the illustration has been provided with the
Painless kit.
10
Fuse Outputs
The Fuse Output wires are all striped wires with the main color of the wire
corresponding to the color found on the Fuse Input wire. The 10 Fuse Output wires are:










PINK/BLACK- “FUSE 1 B+”
PINK/WHITE- “FUSE 2 B+”
PINK-RED- “FUSE 3 B+”
ORANGE/BLACK- “FUSE 4 B+”
ORANGE/WHITE- “FUSE 5 B+”
ORANGE/YELLOW- “FUSE 6 B+”
RED/BLACK- “FUSE 7 B+”
RED/GREEN- “FUSE 8 B+”
RED/WHITE- “FUSE 9 B+”
RED-YELLOW- “FUSE 10 B+”
The power source a Output wire carries is determined by the power source the
Fuse Input is connected to. These Output wires will connect to components needing a
power source. All Output wires are 14 and 16 gauge wires. The larger 14 gauge wire
will handle up to 30 Amps, although it is not recommended to run more than two or
three components with that high of amperage through the fuse block. The 16 gauge
wire will handle up to 20 amps. An assortment of fuses has been provided to allow you
to match each circuit’s amperage rating to the component being wired.
Relays
The 2 large 40 AMP Relays (Relays 1 & 4) and the 2 smaller 20 AMP Relays
(Relays 2 & 3) found on the Fuse Block are each color coded based on the main color
of the wires coming from each Relay.




Relay 1 (next to Fuses 1-3)- Yellow
Relay 2 (next to Fuses 4&5) - Blue
Relay 3 (next to Fuses 6&7)- Green
Relay 4 (next to Fuses 8-10)- White
The stripes found on the wires coming from the Relays help indicate their
function. However, like mentioned before, these wires are also printed with their
function.
11
Relay Inputs
The Relay Inputs are solid
color wires like the Fuse Inputs.
Also, like the Fuse Inputs, the
color of the Relay Input wire
determines the main color for the
wires of the relay. The Relay
Inputs are as followed:




Yellow- “RELAY 1 INPUT”
Blue- “RELAY 2 INPUT”
Green- “RELAY 3 INPUT”
White- “RELAY 4 INPUT”
These Input wires will be
connected to the Circuit breakers
found in the parts bag. More on the Relay Input connections on page 16.
Relay 12 Volt
The Relay 12 volt wires are White striped wires, with the exception of relay 4
which has a Blue stripe. The Relay 12 Volt wires are:




Yellow/ White- “RELAY 1 12 VOLT”
Blue/ White- “RELAY 2 12 VOLT”
Green/ White- “RELAY 3 12 VOLT”
White/ Blue- “RELAY 4 12 VOLT”
The Relay 12 Volt wires provide a power source to the electromagnetic coil inside
the relays which switch, or activate, the relay. The 12 volt wire will be connected to
either a battery constant 12 volt source or to a switched 12 volt source. The power
source a 12 volt wire from the relay connects to will depend on the activation method of
the relay. To determine the activation method that best suits your needs, see pages 14
& 15.
12
Relay Grounds
The Relay Ground wires are Black striped wires. The Relay Ground wires are:




Yellow/ Black- “RELAY 1 GROUND”
Blue/ Black - “RELAY 2 GROUND”
Green/ Black - “RELAY 3 GROUND”
White/ Black - “RELAY 4 GROUND”
The Relay ground wires provide a chassis ground source to the electromagnetic
coil inside the relay which is used to switch, or activate, the relay. The Relay ground
wire will connect to a good clean chassis ground or the negative side of the battery. Like
the Relay 12 Volt wire, the connection of this ground depends on the activation method
of the relay. To determine the activation method that best suits your needs, see pages
14 & 15.
Relay Outputs
The Relay Output wires are Red striped wires. The Relay Output wires are:




Yellow/ Red- “RELAY 1 OUTPUT”
Blue/ Red - “RELAY 2 OUTPUT”
Green/ Red - “RELAY 3 OUTPUT”
White/ Red - “RELAY 4 OUTPUT”
The Relay Output wires
carry power from the relay to the
component needing power.
Examples of components
needing to be wired through a
relay are: electric cooling fan(s),
electric fuel pump, electric water
pump, off-road/driving/fog lights.
Anything that requires an
amperage draw of 25 amps or
more is generally better off
wired through relays. This
prevents high amperage draws through the main fuse block.
13
RELAY ACTIVATION METHODS
12 VOLT ACTIVATED RELAY
A 12 volt activated relay is constantly grounded and will only send power out of
the output side of the relay when 12 volts is applied to the relay, as the name implies.
The 12 volt source can be wired directly to the relay or interrupted by a switch, as
shown in the 12 VOLT SOURCE ACTIVATION drawing.
Wiring directly to the relay would be used in the case of wiring a Fuel Pump relay or
any other high amperage component you would want to run continuously while the key
is in the on position. In these cases, make certain the 12 volt wire you are using is a
Switched 12 volt wire and not a battery constant.
The 12 volt activation wire can also be wired to a switch to offer the user OFF/ON
capabilities. These are the situations a battery constant power source could be used.
This would allow a component to be turned OFF or ON without the key in the ON
position. However, unless a lighted switch is being used, a ground activated relay may
work better to avoid running power through the switch. In the event that a switch is
being used, make sure the amperage of the 12 volt source does not exceed the
capabilities of the switch.
14
GROUND ACTIVATED RELAY
A ground activated relay is just the opposite of the 12 volt activated relay, 12
volts (battery constant or switched) is supplied uninterrupted and the ground wire is
switched. An example of this method is a thermostat operated fan relay. In this case
however, a thermostatic switch would replace the switch in the drawing below. Like
mentioned before, the ground activation method is best used when a component is
operated by an unlit switch from the interior of the vehicle.
CIRCUIT BREAKERS & JUNCTION BLCOK
Three 40 amp Circuit Breakers have been provided to connect power to Relays.
Each 40 amp relay will be wired to its own circuit breaker, while the two 20 amp relays
will share a 40 amp circuit breaker.
The Junction Block will be used to distribute battery power to the fuse block and
to the circuit breakers. This will help from having too many wires connected to the Maxi
Fuse or from having to make splices to high amperage feed wires.
15
CHARGING SYSTEMS
Being a “universal” style harness and with so many different charging systems
from different auto manufacturers, Painless has only supplied the Output charge wire.
This wire will be the larger rolled Red 6 gauge wire provided with the harness. This wire
is printed “ALTERNATOR B+ TO BATTERY B+”. This wire will need to be connected
to the B+ lug of the Alternator, by first installing the rubber boot and then crimping on
the appropriate ring terminal.
Additional battery power and switched 12 volt wires will need to be supplied by
you, the installer. A factory diagram of the charging system you are using will be needed
in order to identify addition connections that may be needed to the Alternator and/or
Voltage regulator. Some common charging system diagrams have been provided for
you.
16
17
TESTING THE SYSTEM
Use a small (10 amp or less) battery charger to power up the vehicle for the first
time to test the circuits. If there is a problem anywhere, the battery charger's low
amperage and internal circuit breaker will provide circuit protection.
 Make sure the
Negative Battery
cable is connected
to the frame or
engine, and make
sure there is a
ground between the
engine and frame,
as well as the frame
and the body. The
Negative Battery
cable should still be
disconnected from
the Battery.
 Connect the Battery
Positive cable to the
Positive side of the
Battery and also
make sure this cable
is connected to the
B+ side of the
Starter Solenoid and
is connected.
 Connect the Battery
Charger's
NEGATIVE cable to
the automobile
chassis, engine
block or to the disconnected Negative Battery cable. Do NOT connect the
Battery Charger's NEGATIVE cable to the Battery.
 Connect the Battery Charger's POSITIVE cable to the automobile's positive
battery terminal lug.
 INDIVIDUALLY turn on each light, ignition, wiper circuit, etc. and check for
proper operation.
 After all circuits have been checked, disconnect the battery charger and
attach the vehicles battery cables to the battery.

FUSE BLOCK TEMPLATE
FUSE BLOCK TEMPLATE
If for some reason you do not want to use the mounting bracket included with the
kit, above is a template of the main fuse block. The template can be used in a through
panel mount situation, such as a firewall .Some distortion to the template image may
take place due to the mass printing of this manual; these distortions will be less than
1/16” of an inch. Slight trimming may be needed once all holes, indicated by the
shaded areas, have been cut because of this distortion. To avoid possible trimming,
screw hole sizes could be enlarged to ¼” and cuts could be made 1/16” outside of the
shaded area.
