YO guys, trying to connect the adapter für the vol up/down controls on the steering wheel on my 2002 350Z

but the pre owner cuttet the whole connectors and wired them directly to the ISO

Now im looking for help.

• I dont know where i have to connect the Purple,white and gray cable from the remote control.
  
• the Red/blue and the red/yellow cable are chopped (OEM) what are these for ?
  

1. the orange illumination? from the radio isnt connected
   
2. Green/white Antenna is chopped
   

The OEM cables which are connected :

Light green OEM - RED (radio)

yellow OEM - yellow (radio)

Green/yellow OEM - Blue (radio)

For the speaker im running an AMP RCA, so i dont need the Speaker wires

The radio is working, but what with the other things ?
