the ignition switch WHITE wire is connected to the coil... which is why I connected it there in the first place.I think I may have some issues, the previous owner had the WHITE wire spliced into a aftermarket ballest resister, and an electric fuel pump in the ENGINE BAY! so off the get go i'm not exactly sure why or where the WHITE ignition wire should go... straight to the coil? if so then isn't that the optimum place for the fuel pump?
White wire straight to the coil is fine, provided you have a coil that is designed for it. The original coil would be; but the aftermarket ballast resistor would suggest that some previous owner substituted a more-readily-available "ballast required" coil. If so, you need to either keep the ballast, or replace the coil.
Electric pump in the engine bay will generally work fine; but as noted, towards the rear of the car is a slightly better place for it.
The little Facet pumps that I like only draw about 1 amp, so there should be no concern over powering it through the ignition switch. However, a fuse would be a good idea, as the "white" circuit has none and hence is more prone to let the smoke leak out if there is a failure.
However, some other electric pumps draw substantially more current, so a relay would be a good idea for them.
In addition to the fuse, you really should have some device to stop the pump in case of an accident. There are several ways to do this; the most elegant IMO is to use a Bosch relay that senses the engine turning and disables the pump a few seconds after the engine stops turning. They are kind of expensive new,
