I have a 1990 Firebird Formula and need to get to my PROM. I am having trouble opening the ECU because I can't take the box apart without using a lot of force. I don't know if its safe to take those things out of each corner so I haven't tried it yet. It does not help that I don't have anything to fit in there.


EDIT: I looked around and found a fitting for the screws in my toolbox and I don't recognize anything inside. Can someone point out what numbers I need in order to get a new PROM?
