I learned not to play with electricity about 40 years ago when my dad was changing the blade on the lawnmower.  He told me to hold the spark plug wire so it did not make contact with the plug.  Unfortunately, he did not tell me to hold it by the insulated part of the wire.  The blade turned and  . . . arm still hurts everytime I think about it!

Anyway, I looked at the diagram and it look fairly straight forward.  I assume this will work on a Cavalier USS 8 64?

Can really screw the machine up if I do something wrong?

What gauge wire should I use?

Where is a good spot to hide the switch so it will be accessible but not show.  I want to avoid making any visible holes on the machine.

THANKS!
