Need help withe central electric locks

Hi guys.
I recently purchased a 97 s10. The central locking system is not functioning so I tested each solenoid (they are fine when I apply hot and grounds to them and reverse the polarity as well). I then realized that someone had previously installed an alarm system and removed the original wiring. Ok, fine. I'd like to rewire without the alarm but I cannot find a wiring diagram nor can I locate the original power door lock relay. Can anyone help with this?

Thanks,
Mike
