I didn’t like where I put the first ground bus because it made the wire runs to it awkward to run. I left it in place but removed the back side so there are no forest of tabs on the inside. I installed this forest of tabs on the left side of the firewall next to the passthrough. I will tie the old bus and this new bus with a single thick wire. There will be two paths; the cable and the firewall. I doubt this will cause any issues.
