The spot where the arrow is pointing to, i think the wire is disconnected. I tried putting the wire back into the brown thing [i dunno what its called]. But it wouldnt work, i tried to take apart the brown thing out but it was impossible. How can i fix this guys ? i think the third picture shows clearly wuts wrong with it. thanks

 

Buy a replacement plug. Try your dealer or a local electronics store.
You can probably find them on-line too.

 

I'm sorry, i'm a newb so im not really getting this. Can i buy this replacement plug from place like AutoZone, Pepboys or Kragen ? thanks

 

You could try a junkyard for the part. Then color-match the wires, cut and splice.

 

anyone know the NAME for that specific part so i can search ? thanks

 

Driverside front turn signal harness and socket maybe?

 

Turn Signal Lamp Socket Assembly: Part # 26243-66Y00

Should be about $9-12 at your local Nissan dealer.
