PREPARATION FOR INSTALLATION
Before dismantling your vehicle, we suggest you prepare
all your components, enclosures and wiring harnesses. It
increases efficiency to have everything ready when each
component is installed.
STEP 1 – CONFIRMING POWER TO BUS BAR
(Applies to 2013-2018 RZR Models)
The Polaris RZR has a harness that connects the battery
under the seat to the bus bar harness located under
the hood. The bus bar is typically where aftermarket
accessories easily connect.
The harness is shown in Figure 1-2. Check that your
2013-2018 machine has this harness installed. If not, you
can purchase from your dealer or Polaris online. The part
numbers are 2881551 or 2881646 depending on which
specific RZR model you own. 2018.5 Turbo S and all 2019+
RZR models already contain a bus bar harness.
The bus bar is the recommended location to connect
the NA2-400.1 amplifier’s power and ground wiring.
