Allows easy access to factory radios with built-in rear speaker outputs
Plugs directly into an empty 35-pin socket on back of radio
4-pin plug also plugs into rear input on NCA 450-AA amplifier
Wires are clearly labelled for easy installation
This plug accesses the speaker leads of the radio but does not activate your radio's built-in fader control. To have your fader enables, you must go to a Harley Davidson® dealer and have your radio "reflashed."
