Dc jack & battery snap with a negative voltage inverter (Rnge Mstr build)

[jball85]

So I've got all of my parts together for this layout, with the exception that I'm using an OC44 instead of an NPN transistor for which the layout calls. And this is important, I would like to use a negative voltage inverter to keep the ability to daishy chain, but still use both a DC jack and a battery snap.

I can't find any wiring diagrams for using a voltage inverter with both dc jack and battery snap. If anyone has one I'd appreciate it, this one has been taking my mind for a spin.

Here is a link to the layout,    http://turretboard.knucklehead.dk/2011/02/28/terminal-npn-rangemaster-with-mods/
