If you have it, it connects to the brass connector above the blue connector in your left picture.
If it never worked since you bought it, here's what I suspect may be happening:
If you don't have the antenna cable, then your car was not originally equipped with remote key fobs. It could very well be that your car was not so equipped, and the previous owner may have replaced the original M531 Immobilizer with an upgraded M535 version, and added remote key fobs. Maybe he got them as a package deal. If this is the case, then maybe if you find an antenna and cable from a scrap yard you can get it to work? I don't know for sure though.

Thanks Piper, I have the antenna and I took it off from the ACU, but now when I try to remember of it, there is a chance that the antenna cable could have been better installed in the ACU socket. Hopefully this was the issue... I'll find it out probably on next weekend when I plan to re-install the ACU
