Curious on why you had to get the box updated Emil? Is there a new version?
I had small issues with wiring also Alex. I ran the fattest cables available back to the trunk battery for both positive and negative to start. Then my Gold Box gets a direct wire to the positive post on battery.
As for grounds using 4 ga. cable I tied the heads and block to a ground bus bar which ties to the negative cable back to the negative battey post. Gold Box grounds to the heads and all other grounds run to the bus bar.
No issues with starting/ running
Thats where I messed up. I ran 0/1 g welding wire for the positive and a short wire for the ground. I need to overdo the grounds and run a bus bar to the grounds up front.
