Default Rear impact sensor??
Hi guys, I've been on here for a long while, with this being my first real post. Can anyone tell me what the heck goes here? I can't find it on any diagram, and my intuition tells me that it's an impact sensor..

Thanks for the quick response. Yeah, that was my first thought as well. The parking sensors are all along a single loom, and all have male connectors - just like this plug.


parking sensor

mystery plug

I'm thinking that it would have something to do with what was mounted here. When I got my car, the red circle was MIA. (The green circle is the sensor loom plug)

Does the connector look like a factory set up? Maybe the PO had a radar detector installed and removed it when they sold the car. That wire loom looks factory though.

It's a branch off from the parking sensor loom, so pretty certain it's stock. I'll dig up a wiring diagram tomorrow night.

I am attaching pics of 2008-2010 parking sensor harness, and it doesn't show a branch off. It looks like an after market mod.

I do see something there that the harness leads to which I believe is the trunk close antenna or something.
