Voltage regulator

That is some fancy machining. I put the "isolated field" VR next to my square-back alternator since that space was unused and I wanted to keep the firewall clean. The "ign sense" wire for the VR is a shared run with the field, but 12 awg wire so negligible drop. My "ign" junction is at a PDC relay/fuse box near the battery, so the wires run across the top of the timing cover. I ran a dedicated ground wire to the VR to be safe. In case anyone wonders, that is a Walbro EFI fuel pump and Covette filter/reg at the bottom.
