Take a look at post #187, last pic in that post. I used distribution blocks for my "key on power" and grounds on just my Anteater, ECM, PPE dual pump controller, and nitrous relay in an effort to give them the cleanest ground signal I could. Is that what you mean?
I plan on running the grounds for the higher amp stuff (fuel pumps, trans cooler fans, and rad fans) directly from the battery. I know I had issues with my radiator fans freaking the ECM out when they would run, it would make the truck idle weird.
I have a 4/0 ground from the battery to the block, and 8ga from the battery to the distribution block. Same with the power cables, 4/0 from the battery to the starter, and 8ga from the battery to the ARC distribution box.
