2006 - 2011 H-D BOMM SINGLE SEAT INSTALLATION
Remove your main fuse before you do any thing. This is always a good practice when you play
around with wires. I’m not responsible if you screw something up.
Remove the front cowling and disconnect connector 28A from the back of the radio. This is the
connector on the right of the radio looking at it from the rear.
Remove any plastic wire conduit from the wire bundle to expose the wiring. You will re-install it
when you are finished.
Identify the wire for your model year bike.
If your bike is a 2006 thru 2011 (Harmon Kardon Radio) you want pin 9 on connector 28A.
Looking at the back of the radio this connector is on the one Right hand side.
Note: While soldering the connections is the best and preferred method if you do not have the
skills you can use the supplied Butt Splices. If you want to solder just cut the splices off.
1). Cut the wire that you identified in the above step about 3 inches from the connector and
strip about ¼” of insulation off both ends.
2). Slide one of the 2 Butt Splices on the H-D Bomm over the wire you just cut that goes to
connector 28A and crimp this connection. It does not matter which wire you use.
3). Repeat the above step for the remaining Butt Splice connected to the H-D Bomm using
the other end of the wire you cut and crimp the connection.
Note: If you used the Butt Splices you can wrap them with electrical tape if you wish, but it is
Route the 2.5mm plug on the Bomm to the 2.5mm jack on your GPS unit and plug it in. Use 2 of
the long wire tie’s to attach the cable to the bars. If you have a 660 or 665, the 2.5mm plug is
located on the wiring harness and should be inside the cowling by now. Use some electrical tape
to tie the jack to the plug because it will be a real pain to fix if they come loose.
Replace the Main fuse and test the installation by placing a call. Place the ignition switch in the
Auxiliary position and turn on the Zumo and radio. The radio has to be in the AUX position and
you have to have the audio output of the Zumo connected to the Aux jack on the front of the
radio. The Zumo has to have external power supplied. You can not make or receive phone calls if
the Zumo is on battery power. Make a phone call using the Zumo interface and test the
Note: You do not use the Push to Talk (PTT) switch when talking on the phone. As long as the
radio is ON the helmet microphone is hot. If you do use the PTT switch and your CB is on you
will transmit through the CB.
Every HD Bomm is statically and dynamically tested before shipping. If you experience static on
both ends of the conversation then the problem is with the Bluetooth function of the cell phone or
the GPS. Try moving the cell phone, if it’s on your right hip move it to the left hip etc. Not all
Bluetooth circuits are created equal and the quality of the audio is a function of the Bluetooth
circuits. You can also try deleting the cell phone and re-pairing them. Try pairing another cell
phone to the GPS. Not every has another GPS hanging around but maybe a friend with the same
GPS will let you use theirs to test the installation.
Re-install any plastic conduit over the wire bundle and secure it with electrical tape. Use 1 or 2 of
the long wire ties to secure the HD Bomm to conduit covered cable.
Remember that you are talking via a Bluetooth connection while on a bike. The microphone will
pick up all sound waves, which includes tire, wind, traffic and exhaust noise so the person you are
speaking with will hear this noise along with your voice. If you have an answering machine on
your home phone call it and leave a message then check it to see what you sound like.
