Fuses Help

Hi anyone know what these plugs do? There on the engine harness.

those arent fuses, They're plugs. the top one looks like it goes in the passenger compartment. The bottom looks like the O2 sensor.
And teh middle one goes in the glove box on top of the Ecu. I think its for the glovebox light.

thanks! does the first plug give input to ecu/engine or is it just output? is it required for the engine to work?

[mattdk318i]

not that im aware of. Im not sure exactly where that one goes. Since its a 85,Euro and a 316 it could be something totally different than what im thinking.
But i could sware that goes inside the car under the knee bolster
