1. PCM - under dash, look behind the hood release, ABS module is also mounted here, CCPS - on top of the throttle body, you will see three vaccum lines, one going to the EGR, one to the FPR, and one running under the intake manifold, the CCPS is connected to this line bolted to the intake manifold(you may need to reach it from underneth) - http://www.saturnfans.com/photos/showphoto.php/photo/14837/
2. PCM - no, CC yes
3. a PCM from a 91 or 92 with DOHC engine and auto trans. a saturn dealership may need to reflash it if the donor car has different options.
