If this is the 2nd amp in the system, mount the amp to the
Hogtunes 2CHSP plate and install in your bike.
Step #4b: Mounting the amp For Road Glide or Road Glide Ultra – The amp will
mount to the plate and the plate will mount to the bike as per the plates
instructions. NOTE: Use the harnesses that come in this kit and NOT the
harnesses that come as part of your RG adaptor kit.
WIRING THE AMPLIFIER
Step #1a: If this is the only amp in the bike. On the audio input harness, locate
the yellow/black pair of wires with the male connectors. Un plug the
factory speaker wires on the clutch side of the bike and plug the yel-
low/black wires in to those. They will only go in one way. Also on the
audio input harness, locate the green/black pair of wires with the male
connectors. Un plug the factory speaker wires on the brake side of the
bike and plug the green/black wires in to those. Note: The blue 4 pin
plug with black wires on the input harness is an “expansion port” which
used to send music to a second amp, or is used to send radio power to
run other speakers on the bike. You can see how the expansion port can
be used further on in this manual.
Step #1b: If this is the 2nd amp in the bike and the “1st” amp is a Hogtunes NCA
40.4. Locate the Blue plug with red/black, and white/black wires on it,
and plug this into the “bypass out” (also a blue plug) on the side of the
NCA 40.4. Take the white/black wires on the bypass plug, and plug
them into the yellow/black wires on the input harness of the NCA 70.2.
Take the red/black wires on the bypass plug, and plug them into the
green/black wires on the input harness of the NCA 70.2.
Step #1c: If this is the 2nd amp in the bike and the “1st” amp is also a Hogtunes
NCA 70.2. Locate the Blue plug with red/black, and white/black wires
on it, and plug this into the expansion port (also a blue plug) located on
the input harness of the “1st” NCA 70.2. Take the white/black wires on
the bypass plug, and plug them into the yellow/black wires on the input
harness of the NCA 70.2 your now installing. Take the red/black wires
on the bypass plug, and plug them into the green/black wires on the
input harness of the NCA 70.2 your now installing.

Step #2: Earlier in the install, you located the black four pin plug with the blue/
black and brown/black wires on it, and plugged it into the “ampli-
fied output” on the amp. The blue/black wires will plug directly to the
speaker on the brake side of the bike. The brown/black wires will plug
directly to the speaker on the clutch side of the bike.
Step #3: The orange wire is the “remote turn on lead” and tells the amp to turn on
whenever it sees +12v (.5 amp min.). Unplug the factory center wire (+)
on the cigarette lighter. Plug the orange lead from the amplifier directly
onto the lighter using the female connector. Plug the factory lighter wire
to the male “take off” connector which is part of the amps orange turn
on lead. Important: If you do not attach the orange wire from the amp
to the center wire at the cigarette lighter, the amplifier will not turn on.
If the factory fuse for your cigarette lighter is blown, and your cigarette
lighter does not work, your amplifier will not turn on.
Step #4:
Routing the power harness -For Standards, Street Glide, EG
Classic, and Ultra Classic
For 98-06 bikes, the power harness will pass under the inner fairing
where the throttle and idle cables pass through on the brake side of the
bike. The harness is designed to be routed between the frame backbone
and gas tank on the brake side of the bike ,and come out just behind the
gas tank. You MAY need to undo the back bolt of the gas tank and pivot
the tank up to allow the harness to pass through at the back of the gas
tank. Be sure to re-install this bolt and torque to factory specs! For 07+
bikes, the balance of the main wire harness will pass under the inner
fairing where the main wire harness passes through on the brake side
of the bike. Loosen the tank console and run wires up and over the gas
tank, but under the tank console. There is a provision on the front of the
tank console for wires to pass. Secure the amplifiers harness to the bikes
factory harness’ using zip ties. When correctly installed, the power and
ground wires are the right length to connect onto the battery. Proceed to
Step #6.
