I've never done a Grand Prix, but it's really very simple. You want to run 3 new wires:

Battery negative to chassis (I followed the stock cable path)

Engine to chassis (I made my own grounding kit, so I have 4 different engine grounds)

Battery positive to fuse to alternator positive post.

Use some string to run along the wire paths that you choose, and that will give you the wire lengths that you will need.
