the ecm for a 1998 grand prix is in the air intake box. it is pretty simple to get out, take a look if you need more help e-mail me chexmix_83@msn.com
No, it is hardwired into the ecm and the rest of the car.
Under hood, passenger side, and under coolant reservoir
Where did u get your new ECM? You probably need to have it " flashed" @ a gm service dept. Or a shop with tec2 scanner
