I'll look into the wire question for you but I have to ask a few
questions first.

Did you use solder or brazing rods to make the connections?
Did you pull a vacuum before letting refrigerant loose into the
system?

If not, you need a EPA certified tech. to do this (legally).

If you can remove the cover from the unit and photograph the wires and
where they connect inside, you can get a better answer than a guess.
