First picture is of a charger off a 1997 motor. That'* why the tee. If you cap those ports and setup all the vacuum lines like your 99 was, you will be perfectly fine.
It'* a question of where you want to harvest the vaccum from, the T or the LIM port. Overall it'* all the same though.
How I know the year of the charger, 1996 had coating on the outside of the charger body and a vacuum tree by the TB. 1997 had no coating on the body, only the snout and a vacuum tree by the TB. 1998+ had coating only on the snout like 97 and no vacuum tree by the TB.

Awesome thanks Bill... the tech hadnt even noticed yet, i've been helping him off and on because I love getting involved, and its my car haha... I pointed the differences out and he said we could just cap them, that on my 99 it probably wouldn't matter but i wanted to find out the reason for the extra lines before just capping them off lol
