I have an 09 Ultra. If I put the xm module on the radio under the fairing which harness would I need. There is 3 listed and I think I would need the one that cost 49.00. Any help would be appreciated because returning these things are a hassle so I would like to get it right the first time.

 

70164-06 this is the one you need if you want to be able to use all of the other stuff like cb and intercom
