Locating the alarm wiring harness

My first post here. Just got an 2004 325i and am in the process of bringing it to some sort of acceptable shape. One of the things I'd like to have is the beep confirming locking/unlocking doors. There are several guides on the net on how to do this, for instance this one:

but I can't seem to locate the factory alarm wiring harness. I removed the cabin filter holder and back wall and this is what I found. They say that the factory alarm wiring harness is stuck with some tape to the wall. But what I see in there is only one connector which seems plugged into the firewall (see attached pics).

Is it possible that the factory alarm wiring harness was never installed?

On the bright side I did manage to code the thing so I can at least get visual confirmation of locking/unlocking (flashing signals).
