What are these unused electrical conectors for?

[ford]

I just discovered 4 unused electrical connectors in engine compartment on passenger side over wheel well between firewall and air filter.
What are/were they for?
I did buy used and it had two front bumper thumpers, enough to require new bumpers, but air bag never went off according to the story.

Probably AHC connectors if your truck is non-AHC.
