If you connect the 2 pots in parallel then the resistance will drop.
Check this in order to understand the basics:

Is it possible to remove the pot from the pad and measyre it, then solder your own made pot to the same place?

So you need help designing the power supply circuit limiting the 48v/2A to 48v/0.5A?
Maybe it helps:

Try using another output instead of RB0 or see here how to disable interupts.

You need to get a pulse for every detection from the module.
Also you have to make the MCU determine if there is a real alarm and not trying to delay the module detection.
So the module detects every motion, transfers every motion to the MCU, then the MCU makes the calculations and gives the...
As an alarm system installer 8-) i would suggest built a pulse/time system like almost all alarm systems have.
Assign how many pulses (motion detections) must occur and in what time window.
e.g. if u assign pulses=3 and time=30 seconds, then the PIR must detect 3 motions in 30 seconds, in...
Try to see how many steps the motor take to one direction before go to the other direction (make delays bigger in your code). Is it lets say 3 steps CW, 1 CCW. Maybe 1 of the windings is not connected correctly (you are using a unipolar motor, right?).
See these too...
