My relay for the blue regulator wire is pretty close to the regulator.
I just remembered that I moved my regulator to the drivers inner fender between the firewall and starter relay when I put my HEI in.
Now it's just a short run to the starter relay.
The point was to make the blue wire as short as possible and a little over sized.
That diagram is good for using a relay on it, and the way you are going about it seems fine.
