Installation Instructions

1.  Remove the outer fairing shell, seat, and fuel tank.

2.  By following along the factory wiring harness, route the 

amplifier power harness from the fairing, under the fuel tank, 

and on to the battery.  (removal of the fuel tank is necessary for 

proper installation)

3.  After first disconnecting the negative battery cable from 

the battery, connect the positive (red) lead from the amplifier 

power harness directly to the positive post of the battery. Then 

connect the negative (black) lead from the power harness to 

the same bolt/stud on the frame that the negative battery cable 

is connected to. Then reconnect the negative battery cable to 

the battery.
