I'm not sure on the 08's but on the 05-07 models, it is a group of 4 orange wires with different color tracers on them, in a small bundle, BEHIND the the fuse box under the steering wheel. You have to actually remove the four bolts holding the fuse box in, swing it out of the way, and they're right there.
Hope this helps, I think it's a good possibility that they are in the same place on the 08's might be different colors though
