Unconnected plugs

Can anyone help identify these plugs? I cannot get the photos to upload. They are 3 plugs on the passenger side above the fender well. If anyone has a quick diagnosis it would be appreciated.
Thanks!

AHC maybe??

That's where AHC component would sit if we had [nicer] trucks. You're not missing anything, and some would say we're lucky to have extra space.

Ah, thanks a lot! That makes sense!
