^should be on the left side, next to your fog light switch...
and yes, you can put leds behind the gauge cluster. I put leds into the PNRD321 console, and moved the wires from there, to a distro.... so anything that turns on w/ those, has led lighting. Which is also wired into the gauge cluster. so technically, w/ that setup, and lights i add that turn on when its dark, can all be dimmed.
the bulbs in the cluster are 194s. you can just pull that bulb out and replace it w/ another
www.superbrightleds.com has a bunch of led type 194 bulbs. i'd suggest the inverted. If you are handy w/ a soldering gun, you can do it yourself. I personally have 2 different colors of leds back there, connected to a switch, so i can change the backlighting... Led lights will be brighter then the 194s though, so you might need more then one resistor in line to get the right level of dim, for yourself.
as for the cruise control light... i believe
www.oznium.com sells 3mm leds. which would work in there, as long as its not 12v. If it is, you'll have to figure out how to work a resistor in between. (put a volt meter across the connectors on the bulb you want to replace, when its "on" see what you get) Most people won't do this mod, since it involved playing with the circuit board. you can do alot of damage w/o doing much at all... so its up to you on that one.
I don't have pics of my gauge cluster, but i'm going to redo some wiring friday, so i'll take some then. Not really a "how to" but you can see the finished product and just fill in the blanks. lol
