you can put the ring on the power cable behind the battery terminal, or run it off the top of the fuse box. i put mine on the box, then bent it like the cable to the alt so its not straight up. i also drilled a hole under the cowl, i removed the cowl and under the windshield is where i drilled, then fed the wire in the hole, and it just came out on the pass side floor. ran it down the side of the carpet to the trunk.

a lot of people like to make a hole in the rubber block on the pass side floor, run the wire down on the outside of the fire wall, but i just didn't like this idea, (wires in this block, and running the wire down the outside of the firewall didn't seem ideal to me at all) so i drilled one hole and it all worked out. i should have taken a pic, but things were just moving right along during the day.
