Can I remove the three small metal box's behind front frame/bumper? Airbags?

Well, trying to clean up and engine bay and surroundings.

Behind the front frame rail is three small metal box's with wires. two go towards the passenger firewall. the other goes to the driver fire wall.

to give yo a better idea of where they are located....

there is one in the center, next to the hood latch. the other two are directly behind the headlights.

they do not say anything. I think they alert the airbag. If so I do not need these as I will be installing a aftermarket steering wheel.

is there any downside of removing these? thanx
