I originally bought the retrofit kit and used that controller. When I was working on another project, I bought a front wiring harness that included the OEM controller and I eventually swapped that in an sold the retrofit harness to someone else. I can verify the following with the OEM controller and the level sensors retrofitted to the driver's sided front and rear:
1. When I switch the lights on and then turn on the car, the lights go through a rotation where they flip up and down and then eventually settle in the middle.
2. When I flip on the high beams, the HID bulbs rotate up and supplement the high beam halogen bulbs.
Here's a video:

When I am driving the car, I cannot detect any action. For example, when I go down a hill I would expect the HID's to rotate up slightly to extend my field of vision. If they are doing that the action is subtle and I cannot tell.
The lights did actions 1 and 2 whether I used the OEM module or the retrofit. I forget whether they did action number 1 before I installed the level sensors.
I can send you a pdf showing the work I did installing the level sensors. The is too big to post here, so send me a PM with your email address and I will forward it to you.
If I recall correctly, the fuse in my car was 15 amp and I did not need to change it.
I hope this helps.
