It will work.
98-03 Gen 3 blowers only have the vacuum tee with 3 nipples on the top, big nipple is for brake booster, middle port is for HVAC, vacuum ball etc, the last port goes to the top of BBV. These are all vacuum only sources. Tee the trans vacuum line into the middle HVAC port. DO NOT tee off the MAP/LIM/FPR/BBV line located under the snout of the SC and wraps around both front and back of the SC. These are boost reference lines.
If you get a supercharger from a 97 GTP, they have an extra vacuum tee on the front of them. This is not a vacuum only source, this front tee sees boost as well and feeds the FPR and bottom of the BBV. Again, only use the middle HVAC port on the top of the SC.
