Window Roll Up Diagram

What I want to do is setup my alarm to roll up the windows on arm and roll down with the aux button.  But I would like to try doing it with relays instead of buying a module, if possible (its after christmas and I'm broke:V: but I have plenty of relays laying around).  The truck I have is 2001 Dodge Ram.  If anybody has a wiring diagram or can point me to a website any help would be much appreciated.

Thanks,

Kyle

I am guessing that the modules either use a timer or monitor the current draw to know when to stop running the window motor.  If you put limit switches inside the door, you could use simple relay logic, but the failure of one of the switches could be bad.  You probably don't want to be leaning out of the window when the relay triggers...

Look into the safety features associated with the module --- I expect monitoring current over time could provide for automatic stop if the window encounters an obstruction.
