I don't have a/c or p/s so i figured they have something to do with that.

 

Assuming that's the plug I think it is, it's used for running a resistor box for aftermarket injectors. Don't worry about it.

 

Alright thanks man. Just makin sure i wasn't missing something. cause i bought the car without ac or ps.

 

its not for the resistor box...

its the loom junction connector for earths or positive wires
there should be 2 of them

if i remmber correctly the one with all the Black / yellow stripe are all grounds
and the yellow / black stripe are all positive

 

That may be the correct and technical name for it, but it is widely used to connect a resistor box. That's how my 480s are wired, and that's how multiple write-ups recommend wiring it. In fact, here is just one such write-up.

 

Dead end plug.
