As fender3x, the ‘lefty’ aspect applied to how the pots would be wired on a left-handed build. And, as Trevor confirmed, you are correct with 4&5 to volume, 6&7 to tone 1, and 8 to tone 2.
It’s a little tough to certain from your images, but from what I can see you should have:
-black wire to switch ground.
-white (light grey?) wire to switch 4&5.
-dark grey wire to switch 6&7.
-purple wire to switch 8.
