front to rear neg. wire runs ????'s

If your grounding points are good, then you shouldn't have a problem with frame. Still do 3 neg runs from rear batts or amps or whatever to frame, and then 3 from frame to front battery or alt or wherever you are going. Though me personally, I'd do dedicated runs if you have the space and cash. Remember to fuse those as well. It's also possible to do a combination of the two, maybe 1 or 2 runs and then ground to frame. Just remember to have the same capacity at the termination points like I explained above.

I ran 3 runs of positive and 3 runs of negative.
