Unknown Sensor that is unplugged


New member
Hey guys! I had a quick question.

So I was digging around in my engine bay doing some stuff and I found this plug that was unconnected. It looks like a sensor that should be plugged in somewhere...


Does anyone know what this is and where it might belong? I am currently having an e-brake sensor problem, but I think it is unrelated.

This is on a 2002 T1N Freightliner Sprinter 2500.

It always helps to tell us the wire colors, as well ... they help confirm a guess by looking at the wiring chart.
