Here is a couple of pictures, cover on and cover off. There is a large ground terminal right next to the positive one. You can see it in the pictures.Do you attach the negative cable too? If so, where does it attach to?
I believe the negative terminal under the hood is just outside of that picture. It would be to the bottom left of the picture and looks like a metal bar sticking out from the fender.
Just FYI, the trunk light will go off after a few minutes. :wink
