Repairing my RDX and I have this harness Behind the bumper. One part goes to the smart key antenna the other I assume is the smart key buzzer but what is the last part? Here are some pictures if anyone can help.

 

 

We're going to need closer pics of the hardness in order to be sure..

 

Could it be the "Beep-Beep" when the hatch opens and closes?

 

It's not the buzzer. It is part of the same harness the buzzer is connected to. The harness connects to the buzzer the smart key antenna and the mystery part. I have been looking for a picture of a RDX without the bumper but no luck.
