Yes, all you need to do is pull the lamp voltage off the factory harness. The trick though, if I remember correctly, is that the factory harness dims the negative side of the circuit as opposed to the positive side like you'd expect. This means you need to run wire to both sides of the switch as opposed to just using a single positive wire and grounding to the chassis normally.

These are the two wires you want behind the factory dimmer switch although I don't recall which one actually dims:
