Indicator Wiring Details (technical help needed)

Hey all, I'm after a bit of help. I'm looking at designing a product to add a feature to the Z which most modern cars have, and even a lot of older ones, but to do so, I need details about exactly how the 350's indicators work.

 

Ive already located all the wires I need to get this working, but could someone advise on this last stumbling block.

This is a simplified (no BCM is shown) diagram of indicator connection methods, I'm leaning towards the one labelled 'NN' (in this case, the indicator stalk grounds the sigal which the BCM recognises and the lights have their own positive supply, the flasher relay is grounded), but not 100% sure. The PCB I need to build will be different depending on the particular connection model so I need to get this right so I'm calling on the hive mind for assistance!

 

I realise this is ma but technical so realy appreciate any help!
