I was cleaning out my truck (2006 F150 Screw XLT w Captain's Chairs) today and noticed that the front lip of my front passenger seat cover had come loose. While I was trying to hook it back up I noticed a small black box affixed to the frame directly underneath the seat. It's about the size of a pack of cigarettes. There isn't one on the driver side. Anyone know what it's for?

 

my guess is thats part of the seat weight trigger system as far as deactivating the air bag if there is no weight or 90> pounds

 

Doh!

 

bingo!
