INSTALL POWER HARNESS AT BUSBAR (ALL MODELS)

Before positing the system harness and wiring all the components (source unit, amplifiers, subwoofer and
other speakers), you need to prepare the power portion of the audio harness and run into the vehicle.
STEP 1 – REMOVE RZR Busbar FACTORY CONNECTIONS
Remove the connections to the RZR busbar as shown in Figure 9-1 to allow connecting the audio harness
along with reconnecting the RZR busbar harness.
STEP 2 – LAY IN HARNESS - IDENTIFY FIREWALL GROMMET
Beginning at the RZR busbar, 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 final inspection.

STEP 4 – COMPLETE BUSBAR CONNECTION
Complete connections at the busbar 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.
