POWER HARNESS
INSTALL POWER HARNESS AT BUS BAR (ALL MODELS)
You must prepare the power portion of the audio harness and run into the vehicle before wiring and
connecting any of the audio system components.
STEP 1 – REMOVE RZR BUS BAR FACTORY CONNECTIONS
Remove the connections to the RZR bus bar as shown in Figure 9-1 to allow connecting the audio harness
along with reconnecting the RZR bus bar harness.
STEP 2 – LAY IN HARNESS - IDENTIFY FIREWALL GROMMET
Beginning at the RZR bus bar, route the power, ground, and accessory portion of the audio system harness
in the front vehicle. The harness will run through the grommet next to an existing wiring harness as shown in
Figure 9-2. Do not use other grommets if present, empty or not.
Use only the grommet shown.
STEP 3 – CUT OPENING IN GROMMET AND RUN WIRING THROUGH
Using a razor knife, carefully slice the rubber grommet on the top side as shown in Figure 9-3a. This allows
you to move the harnesses into the dash and to the amplifiers. Push the radio, rear speaker/illumination,
and amplifier connections through the grommet as in Figure 9-3b. Leave accessible from the inside of the
vehicle. Use black electrical tape or silicone-based caulking to seal the slice during the final inspection.
STEP 4 – COMPLETE BUS BAR CONNECTION
Complete connections at the bus bar as shown in Figure
9-4. Mount the MB Quart audio harness first, with the
OEM RZR connections on top. This allows you to use
the red boot on the powerline, keeping your install clean
and looking factory installed. Zip-tie this power portion
of the harness into place. Assure that no added wiring
is near any moving parts or components that generate
large amounts of heat.
