New member 03 Orange Svt electrical issue

Hey guys I need your help. I had a faulty upstream O2 sensor and went to replace it only to find two wires that come off the plug on the harness side that were cut and appeared to have been disconnected for sometime. One is black and the other is yellow/black. Any clue what these two wires are for? I was unable to find electrical diagrams so thats why I eneded up here.
