That's what I ended up doing. Just tapped into the wiring for the exisitng dome light, ran the new wires across the top of the headliner, then spliced them into the additional dome light. Now both of them come on, step down (I have LED bulbs in them so the light level doesn't fade out), and turn off together. I can also tap them on/off as necessary.

Nice job on getting the additional accessory plugs in, by the way.
