does anyone know where the vac hose connects to on a 97 grand prix super charge

Do you mean the vacuum line? Their are four connections to the S/C. One is driver side behind the S/C underneath the MAP sensor[L fitting], the second connects under the snout of the S/C [T fitting]. The third connects to the fuel pressure regulator on the front of othe S/C [t fitting]. The last connects to the ______(forgot what its called) on the right front of the S/C [straight fitting].

Someone confirm this please.

I'll confirm you are about 50% right. 96 and 97 had a vacuum tree by the TB that added two ports. IIRC One feeds the BCS and the other feeds the FPR. The LIM port only feeds the map sensor in those two years. When 98 revisions happened the vacuum tree disappeared and the vacuum line became a horseshoe that supplied all vacuum.
