Okay thx I’ll check into it today. What I can say is that when I connected the two wires off the master cylinder there was a little spark and the alligator clip got hot as hell so I think there’s juice going to the brake switch !

Of course, that little spark means that there is something consuming that current. In other words, something is operating, whether correctly or incorrectly. I'd suggest that the switch itself is possibly grounding internally. Take both wires off of the switch. Check EACH lug on the switch with your ohm meter for signs of being grounded. If one of them IS grounded, you've found your "sneak circuit".

He got that spark by connecting the two wires to each other. Brake switch was by-passed.

This one is a head-scratcher. I have no idea.
