Standing in front of the car, looking down on the engine bay...
As far as the coil pack layout:
5 - 1
6 - 2
4 - 3
Cylinders:
1 - 2 - 3
4 - 5 - 6
If you're talking about making the wires fit from the cylinders to the coil pack, and you used a 3.0L wire kit, it's a tight fit but can be done. If you used ATX wires, there should be no fitment issues at all.
Best of luck!
