At first thought almost certainly won't have the wiring in the doors for EW, check the wires by pulling out the grommet at one of the rear doors to expose the wires within, and see how many there are, if there's just 2 or three then no window supply.
That said the fact it has CL as std(?), they may well be there, as can't see ford making two looms with CL one with EW one without, so you could be lucky, if not easy to do anyway.
It might help to removed the surround around the gear lever, and see if there is a large window switch connector tucked around there ?
