As the power source is really the alternator while driving, the upgrade
should really be from there. You can run another wire from the battery
to the fuse box but the harness from the alternator to the battery cable
connection at the starter is still deficient. A separate ground from the
alternator to the body will also improve available voltage and current.

Subject: Headlight Relay - Do I Really Need A New Feed?

Am upgrading the headlight wiring to add the popular relays.  I have
read about 6 sets of instructions that I found online. Half of them say
to feed the 12 volt power from the fuse box, the other half say to run a
new power wire from the battery post.
Does anyone have more than a guess on whether it's really necessary to
run a new power feed from the battery for this purpose?

Thanks much,
Brent
