I see HD makes a harness to add a wired 7-pin headset for the SG, but I can't find a harness so I can plug in a passenger headset too. Any ideas? Thanks

 

I have posted before on this. If you look at the service manual, in the wiring diagrams, and compare both the non flhx/s to the p&a plug on the riders headset for the flhx/s you will see that it is only missing the wires for the passenger headset. I bought a second rider pigtail for the flhx/s and de-pinned it and placed the pins in the corresponding slots on the original P&A plug (280). It is all wired up and I took it to the dealer to be flashed. I can hear my wife, talk on the phone, use the voice commands....but she can't hear anything. So, I checked everything. Connections are perfect. It is wired as it should be. Checked speaker output for both rider and passenger headsets and the passenger headset has no signal being sent. The only thing I can figure is that when they flash the radio, it is from the left side cover and they read the vin which only allows certain flashes to be available. And for the streetglide, it only turns on the riders headset.
I am still working on it and haven't given up yet. I just need to get with a different dealer and see if someone is interested in going out of their way to make it work.

 

Please let me know what you figure out, with that info I will ask at my dealer as well. I have both headsets and if the wiring will allow it, there needs to be a way for the software to make it work. Thanks very much!

 

If it were only that easy. The dealerships around me haven't messed with too many 14s. I figured out the wiring part (solder three wires, pin three others in corresponding slots). It is a software issue that hopefully they can figure out.

 

There was a thread where j&m audio has the harnesses

 

J&M has the solo rider harness. Same as HD.
