No, the express module is for the power windows.
You didn't say what year your car is, please do so in your 1st post of thread.
93-95 have a theft deterrent module (TDM), tucked way up in the dash. I've never removed one from a 4th gen, but on my 3rd gen, I had to take whole dash assembly apart to get to it.
93-95 also has a theft deterrent relay (TDR) which controls starter operation for vats security. It's tucked under the middle of the dash. You would know it by it's wire colors. 2 large yellow wires, 1 large purple wire, and 1 small yellow/black wire.
96-97 cars use a body control module to control vats. But they still have the TDR to control starter.
