That I know of....
GM only used one module for all cars with this system. (One of those money things...)
I don't know where it is on firebird. On Sunbird it is on the left strut tower on the couple I've seen. Firebird probably has the thing hidden like Fiero does. Look for a hole in the front fenders etc where about 10-12 wires vanish.
If need be take "bandage" scissors and use them to folow the wires from the motors back to the module. (This type scissor will easily cut tape and save wire. Any scissor will work if you don't care about wire.)
