94 GTP Electrical troubles...

Still chasing my tail on this car! Anybody out there have an idea where the VATS module is? How about the anti-theft relay that ties into the VATS and the starter circuit? I started with a no-starter problem on a real cold day and just wired around it as a temp fix. Now I have a run problem, runs a few seconds, then dies. Security light blinks constantly. Tried hotwiring the fuel pump and it's pumping good so I suspect the anti-theft system but can't find squat about it. Any help is appreciated, Thanks!
