Where do i plug it to I have nothing on my harness in that area that it will plug into. also the sr20de I got doesnt have a place for the egr like mine did that came in the nx2000 what's up with that can anyone help me?

it has the plug on it with one wire thats cut and i have no idea where to wire it to???
