I have a mercedes 202, got hold of some stock hid lights (the street legal ones, with all required aparatus), yes they were availlable when the car was being built, though still rare.
I managed to find some new old parts to install this upgrade.
Still missing is the wiring and the control module.
-the sensors looks like simple potentiometer not very linear, but nothing that could not ba solved by and ohmeter and raising lowering the car.
-Wiring the controler not a problem if I use the arduino.
-Driving the electric motors that do the job, is the problem >
. I can only see 4 wires in the connector. So I guess it is a stepper motor (solution used nowadays by the industry) but which wire is which ?
How to test without frying it ?
Someone has experience with black box stepper motor ?
or should I sacrifice open one of the motor ?
