I pulled the top of my dash off and seen a couple of plugins. What are they for?

 

where at???
what size???
how many wires???

 

Underneath the dashthe part that pops offon the top where your heat comes out and stuff.They have 2 wires goin into them. It looks like something clips into them.I dont know if they are for speakers or whatI was just wondering? If you need me 2 I can tell you what color the wires and stuff tom.

 

i think i know what your talking about the small plug on the passenger and driver side that have nothing connected to them.. but idk what there for either when i changed my heater core today i saw them... i have alot of questions like this one cuz it seems like everytime i look deeper into my car i find a onother plug with nothing hooked up to it one day im gonna take a pic of aall of them i found one in my engine bay to day when loosening the bolts for the Core..
