Lots of unused plugs???

[GSXRliterbikz]

So I was pulling the rear hatch apart on my new to me 01 v8 sport. Seems like there was a lot of unused plugs laying around. I know the dsp setup was a bit hacked due to a PO installing an aftermarket sub.
I snapped a few pics. Any ideas?

This one is attached at the middle of the hatch just behind the bumper.



This one is 2 wires. Blue/grey blue/red.



This one I think I figured out. It's the ses plug. I found the blue housing floating around in the hatch. Put it together and popped an ses module on it. VR now works.



This looks a lot like the cdc plug. But it's not. No Ibus wire. I have a similar one in my 7 that used to go to a phone amp iirc.



This is the cdc plug (has Ibus). But I cand find the 6 pin connector to go with it, or an extra dsp wire. I hooked up a cdc, but there is no way to output audio.



This one is mounted by the dsp sub and the passenger tail light.



This one is in a pile of wires on the drivers side hatch. The PO moved everything around. Including the factory amp. It's just sitting down in the hole with no fasteners. The connector in question is the black one attached to the others.



Y help would be greatly appreciated. I hooked up a Bluetooth tcu and antenna. Just waiting for my wife to get back with my car. I left the actual tcu in my trunk. Ses works fine, so I think the Bluetooth should be good to go.
