harness missing conections..??

[arriero4x4]

hi guys,
yesterday night i was checking under my truck and i found that some harness connectors ended nowhere. looks thats somethings missing. these were found in the front end of the truck, between the bumper and the radiator, and one at the tail. The front ones are relatively small, with 2 or 4 pins. The one at the back is a big one. Any advice?. I'll post some pics tomorrow.

thanks

Might be the harness for where you would plug up your truck, some features arent added to the truck but you can add them later. that be my guess if its at the front.
