I found this part plugged in and sitting under the passenger front seat. I tried to find it in the parts book (which I admit I struggle with), and think I found it. But the description, and also any web search, results only in the description "switch". If I had to guess, I would say it is a passenger detection switch that triggers the fasten seat belt light if someone is sitting in the seat unrestrained. But that is a guess. And since I didn't find it in the seat, but rather laying underneath it, I am not sure if I am heading in the right direction. Any insight? Thank you!
