Can this be used to hook up to a 240 v transformer?

No, this unit is for low voltage used with 24vac transformer

I have order this twice and both times it came without the harness, why is that?

what harness? the electrical coupler cable thingy? mine came with

If the switch and pump where to loose power while the pump was running and the valve was open would the valve be able to close?

The Solenoid Valve is normally-closed. So if it loses power it shuts off automatically.

What is the specific type/model of electrical plug used on this? I want to verify it fits the electrical plugs on the Aquatec pump.

Yes it does it perfectly fits aquatec pumps.
