Electrical / Help with which wires need power/ground to control windows/locks on a 1991 4 door 325

Hey guys,

I'm working on a senior design project for my school.

For one part of the project, i need to be able to unlock/lock and roll up/down the locks and windows of a 1991 BMW 325 rear passenger door.

I was searching for wiring diagrams and found

But things haven't worked out so well.

I took pictures of the harness, and I was hoping someone could tell me which wire/combination of wires are required to:

1. Roll up the window
2. Roll down the window
3. Lock the door
4. Unlock the door.

I found on the window harness, that if i ground black, and apply power to blue, the window rolls down, so I took care of #2.  But I can't figure out the combination to roll it back up.

The locks are scaring me though, i thought it would straight forward, black for ground, white for unlock, blue for lock.  But when i apply power to blue or white, i just hear clicking sounds...and now the mechanical lock itself (the pull up and push down) is stuck??  The handle is stuck too...so I assumed it's locked.  But yeah like i said above...i can't pull the latch up from the inside to unlock the door =.=

Hopefully someone can tell me the appropriate combination (colors) needed to get this to work.

Locks (maybe window?), we have:

Blue
White
Blue/Green (Thick, along the ring)
Blue/Green (Thin, in the center)
Black
Black/Yellow






Window, we have:
Blue/Green
Green/Blue
Black/Yellow
Black
Blue (hidden behind the blue green, left one)




I NEED to have this done by this friday...so please, hopefully someone can help me out.

Thank you!
