Not all of them had one. As I recall they were mounted in the radiator and battery compartment just forward of the batteries and and even with the bottom of the radiator.

So, I picked a random 320D. The diagrams below show the electronic pattern changer manifold. The pattern is toggled through the display monitor controls. All four circles surround the same manifold.Screenshot_20200331-181852_Chrome.jpg 20200331_182013.jpg 20200331_182050.jpg
