I have 2 little grayconnectors one is by the egr valve, and the other is by the alternator... My question is what are they and I dont' really have a pic sorry.
Best guess would be the radio filters. If they are the C shape and attached to a bracket, that is most definately what they are. These usually mount on the front of each head on either side of the alternator.
The year of your car would help and just to double check, these are both dead ends in your harness?.?.?... They are not connectors or plugs?
