yeah i installed it myself but i only wired it so it only does the drivers window cause i never really have others in my car. the one i fitted i put the module box under the centre console close to the power window switches. my one needed 3 wires which went to constant power which i got from behind the fuse box which was a thick red wire i think, an earth wire which i just put to a bolt with a ring terminal and a trigger wire which you can find by removing the side panel at the end of the dash and you will see a plug which then goes into the door, you can use a test light to find which wire lights up when you lock the door and just tap into that wire.
For the window wiring you need to use a test light while pressing the up button on the window switch and which ever one lights up you cut that wire and there should be 2 wires coming from the auto up module, on mine one wire had a fuse holder which was wired to the motor side of the cut wire and the other wire from the module went to the window switch side of the cut wire if that makes sense.
then you just do the same thing for the rest of the windows which is all done at the centre window switch
