You can find them here and there. I got mine from Broggy. Then while working with it I think I found out there is a difference in the harness between his year and mine. Something screwy, would have to go check some threads here maybe.
Also depending on what blue-tooth headset your using you only need one "dongle" The harness runs around $120 or so and they get almost $100 for the dongle. So it is a pricey way to go. I did build a harness to use a "off the shelf" blue-tooth transmitter that worked OK. The bugs I had with the off shelf was could be finicky to connect and it was rechargeable, but could not be used while recharging. The OEM SENA can be a pain to get to connect. The more you use it I supose it gets easier. I really only use it when the wife and I ride for the most part.
Now for the headset I use is a SENA SMH10. It has the "music share" option, so once I connect to the bike audio, I just have to mash the buttons to make it connect hers also. SO no need to really have 2 of the $100 dongles. Here is one on e-bay
, check years for correct part number. What year you need for. I dont remember if I just bought a new one or swapped pins around.
