I have done the SDS hack for my retrofit RNS-E, so just need to connect the microphone lead from the footwell connector to the back of the RNS-E.
I know that I can just add the appropriate pins to connector C in the existing quadlock, but I would prefer to make up a new mini loom consisting of a new male and female C connector and run the appropriate cables to that.
This has 2 advantages for me:
1) I can make this up on a bench rather than fiddling around with the connector in the dash to find the correct pins.
2) If I need to revert to the factory-fit Symphony II, for whatever reason, it is plug and play reversible.
I know that the C connector unclips from the quadlock so all I need is a male and female C connector block and the appropriate pins, and I can make up a loom that clips into the quadlock , connects to the existing C connector, and provides the MIC in connections to run to the footwell.
Does anyone know who makes the C connector blocks and pins and where I can get them from?
