Update:

I removed the top cover...
The ESC was potted/filled with epoxy. Clear epoxy.
The only thing I could do was attempt to strip the couple milimeters of wire that was exposed. I used an exacto knife to slash away a but to expose some wire.
I stripped and tinned the long wires and left some sxtra solder on them. I was able to spread the tiny wires away from each other just enoguh to not have them touch. And just went for it!
Plugged it in and it worked! I globbed on some liquid electrical tape to protect and keep them away from each other.

Of course, 3 minutes into my victory drive, I stripped out something in the tranny!
