There is no point in "enabling" the window relay (which will draw some current) if it's never going to be deenergized. Just remove the relay and jumper the receptacle with a heavy gauge wire. Or remove the relay receptacle and splice the primary wires together.

To clarify: By enabling the relay, I should have said with a momentary push button switch, for the duration you need to open or close the windows.

No one has a wiring diagram for the power windows?
