It's pretty simple, getting the headlight switch off is the hard part. For that, you need a small screwdriver. Pull the switch out, and rotate it around until you can see the slot in the "neck" of the switch. Insert the screwdriver into that slot, then pull towards yourself and the headlight knob will slide off.
Pop the plastic trim pieces out of the black dash bezel and remove the two screws hidden under the trim pieces.
Tilt the column down and gently pull on the bezel until the retainer clips pop loose, lift the bezel out far enough to get the WTS cluster and headlight switches unplugged. The headlight switch plug can be a pit of a pain to get off but not bad. The WTS cluster has a small latch facing toward the driver's door you have to push down on to get it to release.
Once the bezel is out of the way there are 4 (I think) small bolts holding the cluster in, remove those then lift the cluster out and unplug the electrical connectors on the back. If your truck is an auto you'll also have to unhook the PRNDL indicator cable from the column, which is very easy to do and once you get a look at it you'll see how to get it off.
