MSD Wiring w/ Trunk-Mounted Battery

I’ve always done what they say to do in the instructions. I hook the power and ground straight to the battery. If it’s a longer run than the wires they provide, increase the wire size.

The way I see it is the battery is like a large capacitor and it dampens the electrical spikes and differing voltage frequencies. Thus making it “easier” on the ignition box. I dunno maybe I’m a dummy.
