Definitely - if you use Struckby's kit, it comes with the grounding cable. I used the Napa cable upgrade kit, 4 ga. pos (fused) & neg cables, p/n 13-31K.
I repositioned the cable and now the battery light is off. I'm hoping that's all it was. Now on to diagnosing what's wrong with my windshield wipers and a parasite that keeps draining my battery. *sigh
Thanks for the help guys!
