This is the Omega AU-93-4 power window control module, for four windows. Wire it to your remote starter or alarm's auxiliary output and your windows roll up when the vehicle locks or arms. Leave a window down, walk away, and the car sorts it out rather than you discovering the problem after it rains. It's a security fix as much as a convenience one. An open window is the easiest way into a car, and no alarm helps if there's nothing to break. Features Controls four windows in one direction, up or down Heavy duty high current outputs Safety motor cut-off if resistance is detected, so a jammed window stops rather than burning out the motor Accepts pulsed or latched inputs Instructions included Your security system must have auxiliary outputs to drive this module. Only need two windows? See the AU-93.
