I'm trying to use parallel port controller to control some car switches.(such as door , alarm , and more)

the problem is the controller is just relays , it can only turn on or off constant power. But for example , a door switch needs short pulse power (0.5 or 1 sec) .

And I was wondering if there is a simple way to make this work. ??

any idea???
