There's a MAP sensor right next to it on my '88. I don't know if one belongs there on a '95.

Electronic spark control module (ESC)I'm sorry I don't have any answer but am curious what this is that I circled. I have a 95 5.7 tbi and have vacuum issues myself possibly due to the person who had the truck before be trying to so call delete things and took alot off.
