Connect the wiring to these pins, and make sure you wire the Parrot wires appropriately - there will be three from the Parrot
Pin 6 – Telephone audio input signal right, negative - Connect this to the WHITE wire
Pin 10 – Telephone mute (mute switch for radio) - Connect this to the YELLOW wire **
Pin 12 – Telephone audio input signal right, positive - Connect this to the RED wire
Crimp or solder them together, then pop each wire into its location in the housing. Youll need to pop the housing out its holder by sliding it out - its easy when you see it.
** The MUTE wire may not be connected to the radio at present - follow the loom that comes from the parrot to identify the mute wire. Its normally yellow on parrot kits, and connect this as above.
On the RNS510, if you dont connect the mute, it wont work
so make sure you connect it!
