1. Well be careful with your spelling. "gray Bill" wire?? Don't know what that means. Probably Gray/BLK stripe wire.

2. Wire nuts, no good. Someday change to crimp splice or a connector.

3. Confirm you have three wires going back and they come from the right places per my explanation and diagram.

4. You traced GRY/BLK to brake switch. You say "in tact". In tact is not good enough, does it go from the T/S switch to a terminal on the brake switch?
Is there a wire on the other terminal of the brake switch? Where does it go? Specifically.
The brake switch has a always hot wire to one terminal and the other terminal goes to the T/S switch to be routed to the rear. All it does is switch a hot wire on and off when pedal is pushed. So use your ice pick tester right on the brake switch terminals and see if one side is hot and the other is cold. Then pull brake pedal by hand from under hood or operate brake switch lever by hand and see if both sides are then hot. REPORT result BEFORE doing ANYTHING.

5. "Note that this 2 prong flasher’s L is hot with a fuse. The X goes to a yel & Blu wire."
You have this backwards. Not sure you are reading the explanations carefully.... or maybe just a typo. We are taking a lot of time to explain. Post 1537923 says X is hot (with a fuse is OK). L is flash signal and can be spliced to P/pilot on a two prong (YEL and BLU). DAN'S grote diagram shows this also. In all fairness, the flasher may work if wired backwards.

I'm getting "indigestion" !!!!!!!
