Unplug it now.  Ever hear of the Darwin Awards?

If you're asking the question, you shouldn't be doing this.  AC
voltages are deadly, and frying the 'Tron should be of far less
concern than frying whoever is playing the 'Tron.

This needs to be done by someone who understands AC wiring, and knows
several ways to double check their work (as the wires might not be the
intended colors).

EXTREME DANGER...

DO NOT USE THE TRON WIRED AS YOU DESCRIBE.

As wired that sounds lethal probably making some of the innards live!

British wiring code is:

Brown = live (or hot)
Blue = neutral
Green / yellow = earth (or ground)

I seem to remember that US wires are green, black and white for earth, live 
and neutral so you should be able to make a lead that sorts this out. If in 
doubt ask a qualified electrician as mistakes can kill...
