Z4 ECU and Harness plug

I know probably a dumb question but where is the engine control unit located on the 2004 Z4 Roadster 3 litre

Also my car was missing the audio amp when I bought it, I am assuming the previous owner had the amp fry and chose to listen to the motor instead of tunes.
Anyway there is a single round plug that comes out of the amp harness that has no where to go on the new factory amp I have.
what is it for?


Thanks
Dave

Thanks Walter but way too technical for me.
Just want to know what the plug is for I will post a snap shot tomorrow for clarity.
Thinking maybe electric antenna(not used) or ground(not likely)

ECU is in the engine compartment, right side of the car (looking from the front) in a black plastic waterproof housing just in front of the firewall and just to the right of the brake reservoir.

I do but I need better pictures. Does the plug have two or three pins. They could be circular pins?

PS. Walter E. Williams is a noted economist and conservative.

That description does me no good, really.

It could be X1770 that runs from the right Satellite B-pillar module (SRS AIR BAG system) to the battery safety terminal generator (think pyro knife)
