while changing the low tone horn on my car, i noticed two wires hanging in the breeze. this location is behind the right front bumper and fog
lamp. two wires go to the horn. two go to the fog lamp, and the last two look like they went to something that got ripped off, probably when the splash guard was lost.
on the left side, this last set of wires go the the outside air temp sensor, which is housed in the bottom of the left splash guard. there is no such housing on the right splash guard. no one seems to know where these wires (one green/black and one green/yellow) went. everything seems to work and there are no failure indications. i cannot find a schematic for the car. anyone have any ideas? thanks-
