Rewiring GE 5KC49 from 220 to 110

I have an early 60's manufacture GE 1HP 5KC49UG907X (explosion proof) that's running fine on 220 that I want to rewire for 110. It's labeled as a dual voltage but there's no wiring diagram, and none of the ones that pop up in a search show the wire numbers that I can decypher.

The wires that I have are P1, P2, T2, T3, T4, T5 and J10 (maybe J11?). Colors are (naturally) hard to call with the brown, red, orange all faded to the same color, but I think I have P1-dark brown, P2-dark brown, T2-white, T3-brown, T4-yellow, T5-black, J10-red. I'm pretty sure that it was wired as: J10-T4=L1, T2-T3-T5 tied together, P2=L2 and P1 unconnected (220V CCW). I want 110V CCW.

None of the diagrams I can find online mention J10. Is this maybe a thermal disconnect? There is what I suspect to be a thermal fuse/switch inside.

I can check resistance between wires, just don't really know where to start.

On edit: I think I have it, at least it's running w/o smoke. P1 - line 1, P1,T3,T5 tied together, T2,T4,J10 to line 2

looks right I'm thinking if you want to reverse rotation move J10 to the P1,T3 and T5 junction.

I'm thinking J10 is equal to T8 in a new spec, so reversing would be swapping T5 and J10.
