To get the passenger window to roll down like the driver's you just get the express down module (whatever it is called) and wire it up just like the driver's door. Very simple. As for the windows rolling down after 3 clicks, that is totally aftermarket. The stock remote is the stock remote and does not have hidden features lol.
