Hello,

I'm doing interrior fixes on my 1988 f150 and I decided to fix electric door locks while at it. Passenger side motor was damaged so while I was buying new one they offered me to purchase remote locks for more convenience. I'm ok with soldering and all but very bad at understanding schemas. Schema that was included in the box has many different scenarios and I cant understand how it can give positive signal in one case and negative in another. How to understand which case is mine? For example see diagram B and C. Also in schema D and E it used COM ports for motor but I think NC port should be used instead, am I wrong? As I know jn a rellay you get signal on NC port after you open the circuit
