How many wires are there? If it's like the hypergrounds I had forever ago, I think there were 5. There should be a way to connect 3 to the negative terminal (hopefully they gave you a new one with a spot for the 3 to go on). One of those go to the near-side strut tower, next to somewhere on the tranny, and 3rd to somewhere on the engine block. From the engine block, around to the intake manifold, then from the intake manifold, to the far side strut tower. I think I've heard of some having 6, I'd go to the stock battery grounding point with that one.
