Harness connector missing?

Open the split loom and post the colors of the wires in it please. There are a couple of items that use a 2-wire connector (Oil temperature sender, engine coolant temperature, the knock sensors, vacuum pump) The wire colors would determine where to look but I'm leaning toward the oil temperature. Being a 2015 you can try going into the menu on the driver's info center and look at the various data they show like oil pressure, coolant temperature, oil temperature, transmission temperature and see if the oil temperature shows something like -40. That would tell you it's the oil temperature connection.
