95 eclipse turbo awd - what is this wire? (engine bay)

front o2 is 4 wires, mone of the wires are the same color as the ones in question

car isnt a rats nest anymore, devon (fuzzyfish) fixed that (alarm and safc removal / cleanup)

maf sensor is like a 4 or 6 pin plug IIRC, so its not that

ill look around the engine more later to see if i can spot where it goes, figured id post it and ask simply cause i had the pic, and i wont be seing the car for a few days
