Section 2 - Single Amplifier Installation in Road Glide/RG Ultra - Cont.
2. Locate the power harness for the amplifier. One end has ring terminals and a fuse, and
the other has a 2 pin connector. Using Fig 2.1 on Page 6 for reference, to run the "ring
terminal end" of the power harness through "B". We need it so the 2 pin power connector
is accessible in the inner fairing and the slack can be adjusted later in the installation.
Just in front of the tank, there is a structure that attaches the fairing to the frame of the
bike. The power harness will pass through this structure and exit through the rectangular
opening where the factory harness also exits the structure on the BRAKE side of the bike.
Note: it can be easier to pass the wire harness through the rectangular opening if you
"open" the fuse holder and remove the fuse before passing the wire harness. Loosen
the tank's "chrome console" and run wires up and over the gas tank, but under the tank's
chrome console. There is a provision on the front of the tank console for wires to pass.
NOTE: Although not necessary, the power harness can go under the gas tank if you
choose to remove and re-install the tank. If installing 2 amplifiers, both power harnesses
(and rear or lid harnesses) can be ran now.
With the power and ground wires in the vicinity of the battery, move to step 3 WITHOUT
connecting the amp wires to the battery.
3. Locate the "audio in" harness and plug its 8 pin white plug into "audio in" on the side
of the amp. Locate the amp's "front out" harness and plug it into the 4 pin BLACK pigtail
coming out of the side of the amp.
NOTE: There is a variable gain on the amplifier that allows you to "tune" the amp in relation
to other speakers and/or amps on the bikes if they are added. Access to this adjustment
will not be possbile once the amplifier is installed in the correct position.
4. Using Fig 2.1 on page 6 for reference, locate the 4 bolts around "B" and remove the top
left and top right bolts (only). Also using Fig 2.1 on page 6 for reference, there are 2 large
factory harnesses between "A" and "B". You will have to wiggle the amp on the plate into
place around these harnesses so that the holes on the "legs" at the bottom of the plate
line up with the holes where the factory bolts around "B" were. With the plate in position,
reinstall the factory bolts around "B" which will secure the amp on its plate to the bike.
5. As shown by "C" in Figure 2.1, on the brake side of the bike, there is a 2 pin connector
with pink/pink with black stripe wires going through it. The plug is close to where the
wires enter the brake side speaker cabinet. Separate the connector so there are 2 plugs.
From the amp, take the plug with blue/black wires and plug it into the mating plug you
just separated noting it will only go in one way. Also from the amp, take the plug with
green/black wires and plug it into the mating plug that was just separated noting it will
only go in one way.
