IQ DVD/RSE pinout help

[vaughan14]

Hey guys, I recently had VIM activated and wanted to install a Wii in my glove box.

I have a reverse camera so I spliced into that plug and connected a Composite av plug, which worked perfectly.

I then found the pinout for DVD audio on the X4 connector:
Right + : pin 10
Left + : pin 5
gnd - : pin 6

As I didnt have wires in those locations I found the terminal pins on rs-online (stock number: 681-2783)
I ordered x10 for 11 aud, and they arrived in a few days.

I connected the red and white av plugs to the terminal pins and plugged them into the X4 connector but I am getting no audio.

I have looked at the X3 connector and have see some DVD audio output pins, am I missing something, do i have to connect these to somewhere?

Cheers Vaughan.
