INSTALLATION INSTRUCTIONS
RZRHARNESS3
IMPORTANT NOTICE
When connecting power and ground wires ensure that the red power wire is fused at the
point where it is connected to the vehicle’s battery. Failure to do so can result in damage to
the vehicle if a short circuit develops between the vehicle connection point and the product.
INTRODUCTION
The MTX RZRHARNESS3 is designed to work with the MTX AWMC all-weather media
controller, MUD100.4 Amplifier, RZRPOD65 speakers, MUD65P speaker pods, and RZRXP-10
powered subwoofer in select Polaris RZR vehicles. The harness is designed to simplify
installation of all of these parts for a complete audio system. These instructions are designed
specifically for the RZRHARNESS. See other part installation instructions for details on how to
install them in their locations.

INSTALLATION
The rst step in installing the RZRHARNESS3 is to remove the seats, center console, under
dash, and instrument cluster from the RZR. Once those pieces are removed, a large grommet
located on the forward rewall can be seen that includes the factory wiring harness. After
carefully making a small incision feed the end of the RZRHARNESS3 through that grommet
leading with the end that includes the black and red ring terminals. Please note the fuse holder
will have to be removed in order to get the harness through the grommet. Set it aside until the
next step. Continue to feed the RZRHARNESS3 through the grommet until the orange and black/
orange ring terminals are through the grommet to the under hood side and then stop.
The black and red ring terminals are designed to be connected to the vehicle’s battery and
should be run down the center of the vehicle, following the vehicle’s factory harness. Take
care to keep it away from any moving parts (the drive shaft will be exposed). The kit includes
expanding wire ties that can be used to hold the harness in place using existing factory holes.
At this point the fuse holder can be reattached to the red power wire but DO NOT connect to
the battery. The center console and passenger seat can be replaced at this point making it
more comfortable to complete the rest of the installation.
The next step is to connect the orange and black/orange wires to the buss bar under the hood.
If the vehicle is equipped with a Polaris accessory harness, follow the markings on the buss
bar and connect the orange wire to “ACC” and the black/orange wire to “GND”. If the vehicle
is not equipped with a Polaris accessory harness, connect the orange wire to the same stud
that the existing orange wire is connected to. Then remove one of the T25 Torx bolts that
attaches the buss bar to the vehicle, this bolt is ground to chassis and will be used for the
ground connection. Put the black/orange ring terminal through that bolt and reattach the buss
bar to the vehicle. The black and red wires in this same breakout are for the LEDs integrated
into the MUD65P rear speakers. These can be connected to the same posts as the orange and
orange/black with the red going on the orange and the black going on the orange/black. They
can also be wired to a switch, giving the user the ability to turn the LEDs off when not needed.
Next the harness can be connected to the AWMC3 using the large Molex style connector on
the harness. It will mate to the rear of the AWMC3 and can only be connected one way. The
RZRHARNESS3 includes two sets of RCA male connectors. One is labeled “FRONT” and one is
labeled “REAR”; these need to be plugged into the corresponding female RCA connections on
the AWMC3.
The second Molex style connector on the harness is designed to connect to the MUD100.4
amplier. Discard the female end of the harness on the MUD amplier and connect the
RZRHARNESS3 Molex connector directly into the male end on the amplier. Next connect the
male red power wire on the harness to the corresponding female plug on the amplier harness.
Then connect the black female plug on the harness to the red male plug on the amplier.
The subwoofer will be wired next. There are ve connections for the subwoofer (plus one
small plug included with the subwoofer for the EBC) on the harness: power, ground, remote
turn on, and male RCA’s. Connect the RCA’s from the harness into the female RCA inputs on
the subwoofer’s amplier. Next connect the female red power wire on the harness to the
corresponding male plug on the subwoofer’s amplier. Then connect the black male plug on the
harness to the red female plug on the subwoofer’s amplier. Finally, connect the strip a small
piece from the end of the blue wire on the subwoofer amplier harness. Using a crimping tool,
put that stripped end of the wire into the female end of the butt connector connected to the
harness at the subwoofer.
Connecting the speakers is the next step. The RZRHARNESS3 front channels are designed to
be used with the RZRPOD65 front speakers and have all-weather connections that are easy
to connect. The white and white/black wires can be connected to the front left side speaker.
The all weather connections match the wire harness on the RZRPOD65 and can be connected
easily. The grey and grey/black (positive and negative) are for the front right speaker and can
be connected in the same way. The rear speaker wires are designed for use with the MTX
MUD65P pod speakers so both the left and right leads in the RZRHARNESS3 have both audio
signal and power (for powering the LED in each speaker) wires. The green and green/black
(positive and negative) are for the left rear speaker. Green will connect to grey on the speaker
and green/black will connect to grey/black for signal. Red from the RZRHARNESS3 will connect
to yellow on the speaker and black will connect to black. The purple and purple/black (positive
and negative) are for the right rear speaker. Purple will connect to grey on the speaker and
purple/black will connect to grey/black for signal. Red from the RZRHARNESS3 will connect
to yellow on the speaker and black will connect to black. Since there is a variety of locations
rear speakers can be mounted, these wires can be cut to match the length needed to reach the
desired mounting location.
Finally, the power and ground wire can be connected to the battery. Connect the red wire
power ring to the positive battery terminal and black ring terminal to the negative battery
terminal. Turn machine to “ACC” or “ON” and power on the AWMC3 to ensure all speakers are
working properly.
