window roll up/down

I tried reading all the posts on window rollup/down but am still need a little help. 1. If I have power windows, do I still need the modules? 2. Can I connect AUX2(-ve) from my alarm to the roll-down switch and AUX3(-ve) from alarm to roll-up switch for all doors?   Will this let me hit the 2nd channel on my remote to roll down all windows and 3rd channel to roll up all windows? Thanks.

only if your windows retains power after the call is off. to check this is to use your key, turn and hold it in the lock/unlock position, and if the windows roll then you don't need modules.

i mean "car" not "call" sorry
