Here is the setup I am running on my 454. Purple wire to "S" terminal on starter, big positive wire from the battery to large lug on starter and power to the HEI from the unfused ignition terminal on the fuse block running through a 30 am fuse and 10 ga wire. Has worked great since people on this board recommended doing it this way.

If it were not for this forum I would be stumped at times, thanks.

I may also like your way better Shyguy. I'm going to have to put ammeter across my way and your way to see which way provides the greater power to coil. I would hate to think that I may be getting a weaker spark if it makes a difference.
