Mopar Electronic Pickup Polarity and Rotor Phase
You're doing good. All writing, especially explaining technical subjects, is difficult. Just keep at it! Make as many edits as you feel helps.
It's a good thing to bring up. When looking for something else I came across a post mentioning polarity used by different systems. When I find it I'll put a link here.
Maybe it will help to explain what the scope traces represent and the measurements made. There's guys like Pishta and 67Dart273 who know at a glance, and probably many who have no idea. I'll put myself somewhere in between. Let me try to fill that in and you can correct me.
Here's a picture of showing a reluctor tooth just passing the pickup nub.
Maybe this is too simplistic but if I understand correctly,
when the tooth gets very close to the nub on the windings, the magnetic pull on the tooth causes small shift of electrons in the windings creating a voltage drop and rise.
The top line on your scope shows that voltage drop and rise. Time is left to right
The blue + is where the tooth is moving away and the voltage is rising. (This is voltage across the black and gray insulated pickup wires)
The lower trace, if I understand correctly, is the signal within the amplifier allowing and breaking current flow through the coil.
Kit,
