Step #8: Using Fig 1.1 on page 9 for reference, you will see 2 large factory
harnesses between “A” and “B”. Wiggle the amp/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 PRIMARY amp on its plate to the bike.
Step #9: Take the Secondary amp and plug the second power connector into
that amp. There is a short harness with red/black and white/black
wires. It has a smaller 8 pin black plug, a 4 pin blue plug and a 4
pin “square” black plug that looks like a factory HD plug. Take the
“square” black plug on this harness and plug it into the mating plug
on your bike that has 4 light blue wires going into it. NOTE: The 4 pin
plug referred to was attached to your headlight before your headlight
came out. The small 8 pin black harness will plug into the “audio in”
on the Secondary (front) amp. There will be one blue 4 pin plug left
empty which is there for possible future system expansion. Plug the 4
pin plug on the lids harness into the “amplified output” pigtail on the
Secondary (front) amp.

Step #10: Attach the amp’s brown wire to the negative (-) battery terminal and the
amp’s red wire to the positive (+) battery terminal. The factory battery
wires are also re-installed at this point. When attaching the power and
ground wires, it is always a good practice to do the negative first.
When the positive connector touches the battery, some sparking is
normal. This is a function of the capacitors in the amplifiers charging up.
