is the interior light supposed to go on when i open the hatch

 

the light over the center console? i dont think so, pretty sure mine doesnt. if you mean the actual trunk cargo light, yes

 

ok because when i open my trunk no lights go on and i found a random wire next to the seatbelt on the passengers side that has a four wire connector on it and only two wires going to it just trying to figure out what this goes to
