Okay, So I have this idea to install this window module to my OEM alarm so that when I lock my car and the windows are down, it will roll them up for me.

Now, here's the problem. I have no freakin' clue how to do that.

SOOO, I did a little searching, and I found this..

Will this work and if so what all would I have to do. Trying to get an idea of the work/modding involved before I purchase or start splicing anything.
