JWD - Try running a amp reading on a VTOM both ways at the battery. I agree it is the same in theory, but I can tell you from experience the readings will NOT be the same. Plus the negitive side is MUCH simplier to bypass wire non essentials such as a radio for presets, and other things. That is of course unless you have a fiberglass car. Fought this war for many years, don't think you can talk me into doing it the other way, but I'm open to suggestions.
