Trunk Mount Battery - Wire Routing

I agree, the alternator provides the power and the battery is like a buffer. I had everything wired in to the stud on the starter relay, I was using that as my power distribution block. I have some bad ignition interference on the radio when the ignition is on, and I am in the process of installing a new radio with a small amplifier, so I figured it's time to give the EFI and radio their own home run to the battery. Everything has been working great for 6 or 7 years since I installed the Painless harness. I never addressed the starting circuit at that time, so I figured if I am touching some other wiring, now is the time to upgrade the starting circuit too.
