I got the new parts and the sensor looks the same as the pictures. Why do you use only the arm? It might be obvious when I have the old sensor in my hand but why not use the whole sensor if possible. Thanks, Mike
I noticed that also, when I did mine. I used just the one part though. It is possible the resistance of the sensor is different or something, so I just did what was already known to work. That was close to a year ago and everything is still working just fine.
