its not that hard, just takes some time. there is only one important thing. i dont know if you have noticed, but after a minute or two after you take the key out of the ignition, the gauges drop and start bouncing a little below the zeros. it is very important that the cluster be removed while they are still on zero, and then plug it in to make sure it stays there. heres a basic run thru of the install:
-remove the two screws underneath the dash overhang(in front of gauges). pop each top side of the lower dash paneling off(right underneath the silver trim, on left and right of steeringwheel). remove two 7mm bolts. the cluster trim is now free to remove(make sure to put the steering column all the way down before trying to remove this)
-next, take the 4 10mm bolts off holding the cluster to the dash. reach behind the cluster and unplug the wiring harness. remove cluster from car
-gently pry the 4 plastic tabs on the clear gauge cover up, and remove the plastic face.
-get a marker and mark on the white cluster surface(not the gauge overlay) where the needles are pointing. just follow the tip until you see the white edges, then mark. make sure to have a definate amount of fuel, this makes things much eaiser(exactly 1/2 tank, exactly 1/4 tank, etc)
-with two slim objects (dull knives work great) gently and evenly pry the base of each needle upwards. (only twist counterclockwise if you cant remove by simply prying). pull the gauge face off, and install the new one. repeat
