So I recently bought an 02 audi a4 1.8. Tore the front end apart to do timing belt and water pump. Found 3 plugs not plugged into anything. They are all on the same bundle of wires. One went to the sensor in the side of the ac condenser, the other seems to maybe go onto a bracket coming off the power steering cooler lines. This bracket is broke on my car. I will post a pic of that one. And the last one I have no clue. The far end of the same bundle of wires is broken off so I am unsure of where they broke off at. Looks like it goes somewhere on the passenger side front judging by the length of the wire. Again all of these wires are in the same bundle of wires that eventually goes to a big wiring harness behind the intercooler
