No worries.

Personally I wouldn't recommend wiring these up to open and close every time you run the car. I doubt the motors in the mirrors are designed to see that sort of use.

If you're integrating with an aftermarket alarm, I would simply tie it to an auxiliary channel and try to figure out a way to set it to auto open, but only if it was already closed.

Honestly, a 530T would be a much better option in my mind as it has current limitation built in as opposed to relying on a timer. Just some food for thought.
