Trunk Mount Battery - Wire Routing

On the past one I did, I grounded the battery to the vertical brace in the trunk that also holds the deck lid torsion rods.

Basically what I did.

I also added a 2/0 ground strap to the front of the motor and over to where the bottom of the battery tray support bracket bolted to the inner fender plus a smaller one on the back of the cylinder head to the firewall. Absolutely no problems, starts just like it did with the battery under the hood.
