For sure it did help! Thanks!
Because folks sometimes search the forum, I thought I would include the part numbers to help anyone else:
Bezel: Cougar: C8WY-10852-A, which is the same as Lincoln Mark III rear passenger seat: C8LB-14527-A. The reading light/power window switches in the Mark III are the same as the Fog lamp/Sunroof switches in the Cougar
Switches: Cougar Sunroof: C8WY-15668-A; Cougar Fog Lamp: C8WY-15A214-A. I am not certain about the Mark III part numbers yet, but I have ordered 2 used C8LB-14257-A,B (right/left) bezels with the switches. When they arrive, I will repost their part numbers if they are present. Interestingly, the bezel I removed form my G was a Mark III bezel with switches with no part numbers.
Royce and I have corresponded a bunch, and he notes that a repro Mark III power window (sunroof) switch is all over EBay. That switch has 6 prongs, but the one in my car had only 3, all on one side. Also, Royce pointed out a possible Mark III reading light switch (fog lamp) NOS on EBay, but that one had two larger prongs, whereas the one in my car has 3 small prongs.
When the parts arrive, I will take pictures of the switches and the plugs so that I can clarify what the correct setup should be.
