Where does the solid copper wire on the valve go to, what does it do
and how do you disconnect and reconnect it when you replace the valve,

If it is left disconnected will you get heat.

It's a capilary tube which goes into the heater box on the right-hand
side of the car. You can't disconnect it because it is sealed into the
heater valve, you have to separate the housing a bit and pull out the
sensing bulb. If you kink or break it the valve will be destroyed. If
this happens the heat is either full on or full off with no thermostatic
control.

If you replace a leaking valve and don't want to take the heater apart
(fancy that): cut the old capilairy tube, and shove the new tube in a
convenient heaterhose nearby

You don't have to take it apart, just remove a few clips and pry it open
enough to change.
