This instruction sheet refers to service manual information. A service manual for this year/model motorcycle is required for this installation. One is available from a Harley-Davidson dealer.
Electrical Overload
NOTICE
It is possible to overload your vehicle's charging system by adding too many electrical accessories. If the combined electrical accessories operating at any one time consume more electrical current than the vehicle's charging system can produce, the electrical consumption can discharge the battery and cause damage to the vehicle's electrical system. See an authorized Harley-Davidson dealer for advice about the amount of current consumed by additional electrical accessories or for necessary wiring changes. (00211c)
WARNING
When installing any electrical accessory, be certain not to exceed the maximum amperage rating of the fuse or circuit breaker protecting the affected circuit being modified. Exceeding the maximum amperage can lead to electrical failures, which could result in death or serious injury. (00310a)
The amplifier installed with this kit requires up to 8 amps more current from the electrical system.

AMPLIFIER HARNESS INSTALLATION
NOTE
These tips help make sure all wiring fits under the seat, especially in multiple amplifier installations:
  • Begin routing the vehicle-side amplifier harness from the large 18-way amplifier connector [289-1B], moving forward on the vehicle. The large connector does not fit through narrower passages.
  • Route all wire harnesses under the frame rail to avoid pinching by covers or the seat.
  • Take care to route ALL amplifier harness branches away from spark plug wires. Close proximity induces spark noise into the audio system.
  • When routing wires from one side of the vehicle to the other, tuck harnesses under the frame tray behind the battery to keep the battery compartment accessible.
  • Route the six-way black, pink-wired audio connectors under the right frame rail, into the right side cover. Bundle in front of the ABS module (if present).
1.
See Figure 7. Route the vehicle-side amplifier harness (1) in the saddlebag mounting area, beginning with the large 18-way amplifier socket connector [289-1A], moving forward on the vehicle. Route the harness following the saddlebag support (3).

Figure 7. Main Amplifier Harness Routing
2.
Route the harness:
a.
behind and underneath the frame,
b.
into the battery area.
3.
Use cable straps (2) to tie the harness loosely to the saddlebag support. Use the large hole near the saddlebag rear attachment point or one of the cable strap slots along the bottom of the support.
4.
Temporarily install the right saddlebag into the support assembly. When sufficient clearance is confirmed, tighten the cable straps. Remove the saddlebag.
a.
Confirm that the vehicle-side harness connectors reach the saddlebag connectors.
b.
Confirm that the amplifier harness connectors and harness routing are clear of all moving parts.
c.
Confirm that no contact is made at full extension and compression of the shock absorber.
NOTE
Continue routing the harness to the front of the vehicle.
5.
Locate the amplifier input (rear output channel of the radio).
  • All except CVO: use connector [162A] on vehicle (see service manual).
  • FLHX/FLTRX: 4-way Molex pin side under fairing (may be connected to jumper 69200489 in prior installation).
    FLHTCU/K and FLTRU: 16-way Molex behind passenger seat (may be connected to adapter 69200714 in prior installation).
  • All CVO except FLHXSE: use connector [296A] under seat.
  • 2017 and later FLHXSE: use connector [326A/B].
6.
Models with one Stage II amplifier in rear:
  • All except CVO: connect 4-way pin side [162A] of vehicle to [296B] socket side of amplifier harness. See Figure 16 , item 15 or 16.
  • FLHX/FLTRX: connect via jumper harness 69200489.
    FLHTCU/K and FLTRU: connect via adapter harness 69200714.
  • All CVO except 2017 FLHXSE: connect 4-way pin side [296A] of vehicle to [296B] socket side of amplifier harness. See Figure 16.
  • 2017 FLHXSE: connect [296B] of amplifier to vehicle [326A/B] via 69201092 ( Figure 12 ).

c.
Connect [319A] from the harness provided with the kit (See Figure 15 item 4) to [319B] of the vehicle.
d.
If this is the only (rear) amplifier connection in this installation, connect the [319B] side of the harness (See Figure 15 item 3) from the kit back into the terminating resistor pack from step "B" above. If multiple rear amplifiers are used, daisy chain [319B] from this harness to [319A] of the next amplifier harness. Always verify that the remaining connector [319B] is connected to the terminating resistor of the vehicle.
10.
a.
Locate connector 299 on the vehicle (under the inner faring, see service manual for location). This connector may already be connected to a faring amplifier.
b.
Install 69200921 "Y" (See Figure 14 ) to vehicle side 299, with one end to the faring amplifier harness.
c.
Install the 69201545 jumper (See Figure 13 ) to the other end of the 69200921 "Y" inside the faring. (If a 69201545 jumper has already been installed on vehicle skip ahead to "f" Do not install more than one 69201545 jumper.)
d.
Route the 69201545 jumper though the inner faring and into the wire trough following the Faring harness routing.

Wiring Diagram Information
Wire Color Codes
For Solid Color Wires: See Connector/Wiring Diagram Symbols (Typical) . The alpha code identifies wire color.
For Striped Wires: The code is written with a slash (/) between the solid color code and the stripe code. For example, a trace labeled GN/Y is a green wire with a yellow stripe.
Wiring Diagram Symbols
See Connector/Wiring Diagram Symbols (Typical) . Brackets [] indicate connector numbers. The letter inside the brackets identifies whether the housing is a socket or pin housing.
A=Pin: The letter A and the pin symbol after a connector number identifies the pin side of the terminal connectors.
B=Socket: The letter B and the socket symbol after a connector number identifies the socket side of the terminal connectors. Other symbols found on the wiring diagrams include the following:
Diode: The diode allows current flow in one direction only in a circuit.
Wire break: The wire breaks are used to show option variances or page breaks.
No Connection: Two wires crossing over each other in a wiring diagram that are shown with no splice indicating they are not connected together.
Circuit to/from: This symbol indicates a complete circuit diagram on another page. The symbol is also identifying the direction of current flow.
Splice: Splices are where two or more wires are connected together along a wiring diagram. The indication of a splice only indicates that wires are spliced to that circuit. It is not the true location of the splice in the wiring harness.
Ground: Grounds can be classified as either clean or dirty grounds. Clean grounds are identified by a (BK/GN) wire and are normally used for sensors or modules.
NOTE
Clean grounds usually do not have electric motors, coils or anything that may cause electrical interference on the ground circuit.
Dirty grounds are identified by a (BK) wire and are used for components that are not as sensitive to electrical interference.
Twisted pair: This symbol indicates that the two wires are twisted together in the harness. This minimizes the circuit's electromagnetic interference from external sources. If repairs are necessary to these wires, they should remain as twisted wires.
