Service Engine Soon Light

[PrImEtImE]

my service engine soon has been on for a while now. Not the gas cap or anything like that. I noticed a loose wire that fit perfectly onto the front of the TB. Can't be a vacuum hose, sound familiar to anybody on what this wire (attachment) would be? I plugged it onto the TB hopefully this turns off the light.

Everythings connected properly so the light did shut off after I took it out for a drive
