What are you attempting to do?

Having just been through this, would like to understand your intention to respond in more detail.

Not really, probably in amongst the 1000 other wires in there, I'm assuming your talking about the radio/CD in the middle of the dash.

10yrs is a while ago, I'm lucky if I remember what I did yesterday

The wires you want to tap into don’t go to the radio.
They go to the rhr quarter panel to the BT module, from there an output signal heads forward to the main stereo module.

So if the BT module at the rear is sending the signal back to the factory head unit, which wires are connecting to the BT module from the head unit?

Different signal - And the factory microphone wont work with aftermarket head units either - been through all of this.

Instead I ran the new mic cabling up to the factory location and then fitted the new microphone into the roof console.
