the cheapest way to get all auto windows is to wire those DEI 530t modules(not sure if they came out with a new one), you run 2 pairs of 14 gauge speaker wire, you run it directly to the motors. also with this module, you can wire an aftermarket alarm to it, so when you lock or arm the vehicle, the windows go up, use aux channels to crack it open and roll it all the way. after this install, all switches will function as auto-one touch.
