Poorly repaired and retrofit light switch...maybe wrong one?

Large brown wire goes to B1 on the light switch...it's hot all the time.
Tan/white wire goes to B2, and it's supposed to be hot, but isn't. Fuse #10 no power.

Operating the switch does not power the small brown wires that go to the tail lights.etc. Jumping to the tan/white does work via switch.
Jumping from fat brown wire to small brown wires R operates the tail lights, i.e. bypasses switch.

1. What and where does the big brown wire come from? Can't find it on any diagram..looks correct...is it correct?

2. Why no power to white/tan? Trouble upstream?

3. Can't find part # on switch...could it truly be the wrong switch? Will replace.
