2003 Yukon xl Denali awd 6.0 found a broken wire and can’t find where it goes it runs in same harness that goes down front of engine that the temperature sensor plug comes out of but lil further down it’s broken it looks like it runs off by itself to something but not sure where and with ignition on the wire is hot but while was looking for short I guess it broke off completely black wire and as of right now my wife is walking to work
