a). Remove the FP relay and locate terminal #85 on the relay socket. You could test terminal #85 either using continuity test between #85 and the sensor plate. Or use a 12-volt TL (test light). I find the TL more convenient and practical for this kind of test.
Terminal #85 is a ground connection for the FP relay that goes to the driver-side terminal or pin of the AF switch. The passenger side terminal of the AFS switch is connected to the AFM body and the wire (brown) goes to D- (alternator).
If you decide to use a 12-volt TL which I strongly recommend, use terminal#85 (FP relay socket) as your ground source. Connect the alligator clip of the TL to a known 12-volt source or use the positive pole of the battery. With the TL connected to a 12-volt source, place the tip of the TL to any known good ground for test. Then test terminal #85. It should not lit up (NORMAL). If it does lit up, you got a PROBLEM.
Either the electrical plug is disconnected or the switch is defective.
b). AFS switch test and adjustment. Will do this later after you have done the above test.
Keep us posted.

I tested 85 and it did not light up. So what is next step?
Thanks
