Wat does this wire go 2? Need help asap!!!

Was test driving my hatch when all of a sudden smoke started filling the inside up. We looked n its a wire that goes into this plug that plugs into the ecu under the dash. Wat does this wire control?
It is the bottmom pic n it is the bottom right plug. It says (c442-92 civic) I need a pic of the wiring 4 that plug. The wire that burn was red/black or vise versa.
