Installation Requirements
This kit must be installed:
  • Before installation of the Boom! Audio Stage II Tour-Pak Speaker Kit (Part No. 76000526).
  • After installation of a PRIMARY fairing-mounted amplifier.
The amplifier (Part No. 76000277A) installed with this kit must be purchased separately from a Harley-Davidson dealer.
FLHX, FLHXS and FLHXSE models require installation of an original equipment (OE) rigid Tour-Pak Mounting Rack. See a Harley-Davidson dealer for the correct parts, available separately. Install per the service manual.
ALL models: If installing more than TWO amplifiers, only one AUDIO IN Three-Way Y-Connector (Part No. 69201092) AND one Battery+ Three-Way Y-Connector (Part No. 70270-04A) are needed. These connectors could be included in other kits. Purchase separately from a Harley-Davidson dealer as needed.
DO NOT mix Stage I and Stage II speakers on the same vehicle.
Radio EQ MUST be updated by a Harley-Davidson dealer BEFORE operating the audio system. Operating the audio system prior to radio EQ update will IMMEDIATELY damage the speakers. (00645d)
Radio EQ update using the Digital Technician® II diagnostic tool is:
  • Recommended before speaker INSTALLATION
  • Required before audio system OPERATION.
  • Only available through authorized Harley-Davidson dealers.
Rider and passenger safety depend upon the correct installation of this kit. Use the appropriate service manual procedures. If the procedure is not within your capabilities or you do not have the correct tools, have a Harley-Davidson dealer perform the installation. Improper installation of this kit could result in death or serious injury. (00333b)
This instruction sheet references 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
It is possible to overload the 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. (00211d)
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.

These tips help make sure all wiring fits under the seat, especially in multiple amplifier installations:
  • See Figure 5. Begin routing the amplifier harness from the large 23-way connector [149] (1), moving forward on the vehicle. The large connector does not fit through narrower passages.
  • Route the remainder of the harness forward on the vehicle through the space between the Tour-Pak support (3) and fender (4).
  • Route all wire harnesses under the frame rail to avoid pinching by cover or seat.
  • Make connections [36TB] (right pod speaker) and [37TB] (left pod speaker) during installation of the Boom! Audio Stage II Tour-Pak Speaker Kit.
  • 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 right to left sides of the vehicle, tuck harnesses under the frame tray behind the battery. 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 ABS module, if present.
  • Locate the black, four-way Molex connector [296A] near the back of the underseat area. FLHX/FLTRX models: On a jumper harness coming from the fairing. FLHTCU/FLHTK models: On an adapter harness with two 16-way ([162C] and [162D]) and two four-way ([296A] and (297B]) connectors. With ONLY ONE Stage II amplifier installed in the rear: Remove the plug in the [296A] connector. Connect the amplifier harness. With TWO or more Stage II amplifiers installed in the rear: Plug the audio input harness into connector halves [296A] and (297B] on the interconnect harness (2). Plug amplifier harness (3) connector [296A] into the audio input harness.
  • Confirm that the amplifier harness connectors and harness routing are clear of all moving parts.
  • Route the battery terminal branch to the battery terminals, but DO NOT connect the battery cables now.
  • If more than two amplifiers or other accessories already use the ground post of the battery, use one of the frame ground studs.
  • If more than two amplifiers are installed on the vehicle, ONE Battery+ Three-Way Y-Connector (available separately) is required.
  • Once routing is finalized, secure with cable straps (10) and retainers (1).

Figure 3. Harness Routing
1. Complete Routing harness:
a. Route kit harness forward along frame rails following main harness under backbone.
b. Route harness along the right side of battery cavity between the battery and reverse solenoid. Place the red fuse wire and black ground wire in front of the battery.
c. See Figure 4. Locate the 2-way Delphi CAN connector [319B] (1) under the right side cover.
d. The cap is a terminating resistor pack secured to the electrical caddy. Remove connector [319B] from the resistor pack.
e. Connect [319A] from the harness provided with the kit (See Figure 5 item 8) to [319B] of the vehicle.
f. If this is the only (rear) amplifier connection in this installation, connect the [319B] side of the harness (See Figure 5 item 9) 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.
a. Locate connector 299 on the vehicle (under the inner fairing, see service manual for location). This connector may already be connected to a faring amplifier.
b. Install 69200921 "Y" (See Figure 7 ) to vehicle side 299, with one end to the fairing amplifier harness.
c. Install the 69201545 (See Figure 6 ) jumper to the other end of the 69200921 "Y" inside the fairing. (If a 69201545 jumper has already been installed on vehicle skip ahead to "e" Do not install more than one 69201545 jumper.)
d. Route the 69201545 jumper though the inner faring and into the wire trough following the fairing harness routing.
e. Locate the end of the 69201545 jumper under the RH side cover near the [319] connectors. If a 69201545 is present from a prior install use a 69200921 "Y" under the RH side cover to connect [299].
If more than one amplifier is installed in rear of vehicle, up to two 69200921 connectors may be used.

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.
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.
