ok here you go,its gonna be fun--trust me(old sales line).along the top of the overlay trim there should be screws,and along the bottom there should also be screws.also above your radio pod there are screws there too.you may have to remove the radio pod to get access to these(it's held on by screws also).also advised to loosen steering column bolts under dash to allow room to get the overlay out without breaking it.since the overlay is a big flat panel that goes from the headlight/wiper switches all the way over to the glove box,expect to remove quite a few screws(HAVE I GOT YOU ALL SCREWED UP YET?).once ALL retaining screws are out the WHOLE PANEL comes off.key thing here is--lower steering column by loosening bolts or removing them and look for hold down screws above radio pod that may require the radio pod to be removed.last but not least-----make sure there are no hidden screws that you missed before you go pulling away at the overlay.you may need a right angle phillips (looks like a allen wrench) to get at some of the screws
once you get the cover off,the instrument cluster is easy,remove the 4 screws holding it in place, pull it towards you far enough to unscrew the speedo cable from the back and GENTLY wiggle and pull the grey round plug from the back of the cluster(be extemely &%$#@#$ carefull as not to break the pins on the back of the cluster--VERY IMPORTANT!!!!).
the wipers and headlight switch,gotta pull the knob from the wiper switch(there should be a little release tab on the backside of the wiper knob) and to remove the headlight switch there is a release button on the backside of the switch(you'll have to reach under tthe dash and press it as you pull out on the headlight knob(the shaft will come out with the knob.DISCONNECT BATTERY as you will have turned on the headlights when you do this.
