In previous vehicles I've owned, I know that the wiring for power seats was there, regardless of whether or not you got the option. You should be able to confirm this with a call to a Toyota service facility if you can't actually see the electrical harness plugs under the manual seat.

Any 2004+ Highlander already has the power cable plugged into nothing under the seat, with a constant power on feeding to it. The new seat will literally be three wires and four bolts and should be good to go.
