Help what wires are these

[baconandwhiskey]

I found these two wires after removing my front lower bumper and skid plate they were not plugged in just shoved up there. Car 87 early 325i vert they are on the front left(drivers side) lower

Black one is the obc temp probe and the blue looks like fog connector

Agree on the black one.

The blue one is probably the connector for the alarm horn for the 13 button OBC system.
