While trying to fix the 1st PO's very poorly installed stereo in my 318ic, I had of course removed the existing head unit and started to fix the "spaghetti" behind it... Once I had the stereo out and sorted through and removed any/all non-essential non-BMW wires, I also had to sort out an issue w/ the passeger side woofer in the kick panel....
After sorting and examining things after the clean up - this is what I came across and I'm not sure what these wires are for or what purpose they serve (if any)....
1) In the radio hole:
A) I found a short (2) wire harness. The wires on this small harness are 1 solid brown wire & 1 blue/brown wire. These wires then go into a black square 2-pronged female connector. Hanging off of this same continuous 2 wire harness is also a black square 2-pronged male end w/ the exact same wire colors. The female & male connectors are a direct match and will connect to each other. However, I have NO CLUE as to what connecting them together does (I don't think they should be connected together as it makes no sense to create a "loop"), if these are to "work" something else or if these are just optional connectors for a more equipped vehicle? The back of the male connector has "12v+" embossed into it...
B) I also found another connector that is white and going into it is 1 solid white wire and 1 solid yellow wire. I don't see any disconnected wires anywhere in the radio hole, nor do I see any other connectors, wires or components that would belong to or match this hanging wire harness.
Both of these misc. connectors or small harnesses as noted above in A & B that I cannot identify are coming off the right side (by glovebox in US made vehicles) from within the radio hole. Any ideas?
2) in the passenger side kick panel hole:
I found 1 single wire that is purple/brown. It has a female spade connector on the end of it. It is coming out of the factory taped wiring loom. I looked around thoroughly within the kick panel hole and I do not see any disconnected wires or extra wiring. I also do not see any male or lone connectors this would go to. I checked the speaker wiring digrams I have and don't see this as being any part of the speaker/stereo system. What is this wire for, any ideas?

Pictures would help immeasurably... :)
1A is possibly radio, I can match the wire colors but not those connectors.
1B is radio, it's on page 6500-2, right side, connector C215.
2 I dunno, I found a similar wire when I ripped out that carpet and can't remember where it goes. Does it lead back along the passenger side towards the rear or up into the a-pillar area?

Yes, it goes back (or comes down from) the A-pillar area and it is grouped with an existing harness (it was factory taped to it).
