Hooking up thermostat?

[Lizard licks]

It comes with a cord that plugs into the thermostat and then plugs into the wall. Like an extension cord.

And one more thing I don't know what he means by pre wired I just know the way I see people wiring them is buying the heat tape them 2 clamps and a wire plug connecting them and then plugging it into the wall (or I guess the thermostat) does that work? And what is a probe?
