I have a 98 FLHTCI which I am adding a CB / intercom system from a 97 Ultra. I think for the most part I have the wiring figured out. The only thing that I came across and am not sure is the three pin electrical contecto to the CB Radio itself. I has a black wire, red wire and orange wire. Can anyone tell me which is which. I believe the red is power and the black is ground, if that is correct what is the orange wire? Please advise so that I dont fry this system. Thanks

If anyone has a wiring diagram for a CB/Intercom on any Harley Ultra from 93 - 97 they should work for what I need.
