Thanks for all the replies on adding CB and to my 2015 SGS. I am taking apart the bike now to add the factory HD cb module and J&M cb antenna to my bike. However I have searched how to add passenger communication and Have not found anything definitive. I understand I have to get the control switches from the Ultra Limited and the 7 pin port to plug the headset into. Also have to make a custom bracket for switches and port. I am good with all that expense and work.

My question is this. Is there a harness to go from the infotainment to the rear of the bike or is it there and I dont see it. Or do I need to make it myself. Who has passenger communication on their rushmore Street Glide and can help me? I understand it was easier on the non can bus 2013 and earlier bikes.
Thanks to Scott14sg and offthewall for their informative posts

I am on a mission because my dealer told me I could add it when I bought the bike and now they are telling me no way can you add CB and rider/passenger communication to the Street Glide

 

Our streetglide do not have the same wiring harness as the ultras and maybe even the CVO streetglides have. In the attachment below this is a 16 pin audio connector that says "except FLHX". The only way to get a harness back to your passenger is make one and run the wires off your P&A audio connector #280A in the attachment below.



This is a pic of your harness diagram





[I]This is another audio connector our bikes do not have.

 

Thank you for confirming, I will make my own harness.

 

Have a 2014 Street Glide...............also have rider to passenger wired comms.
Sorry, do not know how it is connected up as the Harley Tech did it.........the only thing is that the passenger cannot alter the volume level by using a switch on the tour pak speaker pod.....it has to be altered in the 4.3 Infotainment by the rider....This may be possible if the can bus switches are used..I guess..............but at least you now know for certain that it can be done.
