BigLew, the primary difference between the 77107-09 kit you installed, and the 77108-09 kit I installed is how the connections for rider and passenger headset, and passenger PTT are made to the 35 wire connector on the HK radio. With the kit you have, a single harness is used that incorporates all of those functions; but, with the kit I used, a non-Ultra overlay harness is used and the rider and passenger headset and PTT switch are separately connected to the NUOH.
Consequently, all you need to do is trace the wires used for the CB from the module to the HK radio, and supply them to the CB module by adding them to the 35 wire connector you plugged into the HK with your kit. Those wires will include those for CAN + and - (which tells the HK that the CB is connected, as well as power and ground, among others. I haven't researched the connector numbers, wire assignments, etc.
But with the wiring diagram, and funtion of the pin-outs (which are included in the HD Touring model service manual) it should be a simple wiring job. If you're going to use connectors for the CB module, you'll also need the parts manual to purchase the mating connector to the module, and supply the pins/sockets for the connectors.
Good luck with your project.
