Which Brake Pad Sensor Clip

[TiminIndy]

I am ordering some brake parts, including new brake pad sensors for front and back. I noticed they had a sensor clip for ~ $3, so I want to get those too. Then I noticed that the different sites I shop on (FCP, ECS, Turner, RMEuropean, etc..) are showing a different part for this. Most don't indicate whether it fits front, rear, or both. I get nothing on realoem.com for this. Does anyone recognize which works for my 2006 E53?
