Window Control from factory alarm
I was looking to get a DEI 530T to roll down the windows when disarming or roll up the windows when arming the factory windows. The DEI accepts a negative pulse to activate the rollup feature. This shouldn't be too hard to do with the door lock pulse. It also accepts a negative pulse or about 3 sec to rolldown the windows. What I need help with is a circuit that will take 3 negative pulses to trigger then send a 3 sec negative to the 530T. This way i could hit unlock 3x on my remote and it will roll down all the windows. If I can get this working the adding a 529T to run the sunroof should be easy.
