I’m new to this forum and to working on my car myself, so please forgive me if posting in the wrong place and for my lack of knowledge. I recently replaced the heater core in my 96 GT 4.6L mustang. After putting the dashboard back in and getting everything hooked up I noticed a vacuum line going to space. I believe it’s the intake from engine. Does this go to the empty connection on the (what I think is the), EVAP purge valve pictured? I didn’t remove it so I’m unsure and afraid to do anything to hurt my car. The check engine light is on, so not driving it until I can figure out how to fix. Thank you for your help and patience with me.
