Electric windows on ce lancer

Hey everyone, just wondering how do i get electric windows to work on my lancer. I have a CE coupe Lancer. Originally the car came with manual windows but I have to replace the doors on it due to someone kicking them in and my drivers door central locking stopped working. I went to the wreckers and managed to find a CE MR Lancer with electric windows. I have bought the doors and got them home to find out that the central locking works again thank God and that the doors are in really good shape with no dents but I can't seem to find out how to get the windows to go up and down..
Any help would be grateful, and thanks in advance

You’re probably missing the power window relay.
