I just installed mine yesterday... here's how I did it:
I taped into the foot well light for the ground on both sides as I wanted the fade effect.
Didn't use wire taps, they are subject to intermittent condition and can actually sever the wire as the wires used are very small (24 - 26 ga). I soldered directly to these wires about an inch back from the connectors:
RED wire at the footwell light connector (both sides)
WHITE wire at the existing connector at the harness beneath your existing sil plate.
Used 22ga wire for the jumper, strip back about 1/4 inch of insulation with an exacto knife about an inch back from the connectors (after gaining access of course, the close out panels just pull right off, the drivers side has two screws that have to be removed, there obvious). Soldier your jumper wire to the footwell light connector RED wire first, re-insulate with tape(black electrical), use some wire loom covering(that black tubing with the slit running the length of it) and route to the door sil harness. Use same method to attach the other end of your jumper to the WHITE wire at the existing door sil connector. You do not cut any wires, just strip back enough insulation to soldier your jumper to it.
take your time cutting the existing tape wrapping the harness and striping the wires, you should not have a problem if you are careful. After making the footwell connection take not to short the jumper when you are routing it back to the sil connector as it will now be your floating ground so will have a positive potential(voltage signal).
Hope this helps... btw i did this on my 2006 350.
Good luck friend.

UPDATE: rewired my sills lights to the door switch. I didn't like that they done turn off except when the car is off. Unnecessary wear on the leds. I can easily change the under dash leds but not the ones in the sills. The fade in effect looked cool hooked up to the under dash leds, but you have to open the door quickly to notice that they actually did that. Most people wouldn't notice. I also believe the overall light output to the sills was significantly dimmer hooked up that way, versus to the door switch.
