Trunk Mount Battery - Wire Routing

I did. To the block. I use this post to go to chassis. I also use this post to go back to dash. Might be over kill.

Grounds are never overkill imo.

For the record, I don't have a trunk mounted battery, but I do have a ground hub in the trunk, the sending unit, tank, and reverse lights are grounded to it, and a ground wire runs from that to a ground hub in the front.
Everything is grounded to the front hub, hub to frame and battery, frame to engine, dash/gauges to welded bolt behind dash, etc.

No more chasing my tail and scratching my head over electronicals.
