adding locks to flush tonneau cover

Hi I'm new to this forum and also to the car customizing world. I need some help with adding powered locks to my new flush tonneau cover for my truck. My truck is a 2003 Chevy S10 with a Checkmate flush tonneau cover. My truck also has a shaved tailgate so my only option to secure my belongings in my truck bed is to install a powered door lock switch on the inside/underside of my tonneau cover. I don't want to drill a hole through my new tonneau cover for manual locks. I have a Viper 791xv 2 way/alarm/remote start system installed. I believe it has 2 AUX output switches. Could you guys help me out on this project? I know a little about relay switches and stuff. I was wondering if you guys can point me out on a diagram. Tell me what parts I need. I'm also trying to do this cheap. hehe Thanks in advance!

bump. anybody got a clue on how to do this? somebody please help. i need to protect my things under my tonneau.
