So, on non-DSP equipped X5s, which wires are you supposed to tap into for the signal from the headunit? I am following the "Add An Amp" DIY posted in the electronics forum. 12V power and ground plus switched 12V were easy to find. Now what do I do?

I have only ONE connector with 12 wires and it's not connected to anything. In fact it is bundled up and securely tied down in the left side compartment with connections for the cd changer, NAV, phone, etc. that were not installed at the factory. So back to our 12 wire connector from the DIY article. The wires to it look like anything but speaker wires. I took a pic of it, as well as the group it is with.
