If the vehicle has one from the factory, the control module is behind the center of the dash. What is happening? Is the vehicle being prevented from starting? Are there any lights on indicating anti-theft?
Interestingly, very few of these came with anti-theft. However, it was an option.
If you feel it is an aftermarket system, that will be difficult for me to help with simply because they are all different and I won't have a schematic specific to it. But I can tell you that often times you will find wires spliced into the ignition switch and at the fuse boxes.
I attached the wiring schematic below for the factor security system. I hope this helps you.
See pics below. Note: I had to cut the pic in half to make it readable for you. But I did overlap the two so you can follow from one to the next.
