Where's anti-theft controller module located?

Just like the title need to find out where the anti-theft controller module located. Is it located in the trunk on the driver's side in a 1998 mustang gt?

Thanks

Don't quote me on this, but I believe the module that's on the driver's side in the trunk is just for the Key FOBs. I thought all of the anti-theft stuff was done from inside the instrument cluster, but I could be wrong.
