I have a couple of plugs under my dash that dont have anything plugged into then the most visible one is next to the hood release attached to a metal plate. I will try and get a couple of pictures up soon

 

one of them is for trailer brake control (i think its gray but not sure), and one on the right side directly above gas pedal is OBD 2 port

 

Here are some pictures of the plugs, I also know which one the OBDII plug is, it is the other 2 that I am not sure about

 

The 2nd picture, KDracing already told you what it is, the E-brake controller pigtail.

The other is the ABS diagnostic port.

Is there something wrong with them ?

Also, you might want to zip tie that relay up to the bracket for the anti submarine panel. Hanging down like that you are asking for problems later.

 

No nothing is wrong with them but I have noticed them for a few years now and was just wandering if there was something that was supposed to be plugged into them or not and yea I have been meaning to tie that relay somewhere
