you are gonna have to goto the defroster switch and test the wire with a DMM or a computer safe test light to see which wire triggers it.

is the button to turns it on in the car momentary? or is it some kind of latching switch? If it is momentary would could solder a relay across the terminals on the switch, so that it is momentarily "pressed" with the relay from the trigger. If its latching... well check if its moentary first that would be easy to do posted_image

yes it is a momentary that activates a timer in the car.
