I FOUND THIS IN A DIFFRENT FORUM> THIS IS AWESOME
I checked into this when I first got my tC then gave up for a while. Then I saw another another tC owner did exactly what I was thinking (Scion Life thread).
I ordered my LEDs last week, Heres ther ones you want
http://www.lc-led.com/View/itemNumber/98
I bought a 20watt/40watt $20 solder iron, some solder, and solder sucker (Didn't really need the solder sucker).
Removed the guage cluster from the car (2 Minute job, just pull on black edge trim, remove one screw, pull out, disconnect plug.)
Pulled apart the assembly. I made marks with tape and an ink pen to where the needles should go back. Then removed the LED's and replaced them one at a time I replaced only the one responsible for lighting the dials, not the warning lights. I heated up one side of the LED's to be removed and lifted them slightley off the board. I repated that on the other side of the LED so it would fall off the board. Then I smoothed out the pad with the solder iron. I place a new one on the pad with a pair of tweezers and re-soldered one side, the the other. There are 14 in the guage cluster. The LED's have a very small cut-off on one corner, that is the side that goes in the direction of the arrow on the pc board. Do one and then you can test it if you like, just to make sure you have the right orientation.
BTW, I chose to leave my needles orange.
Put it all back together and pop a cold beer. Turn on the lights, give yourself a pat on the back.
I will do the console next week then add instruction to my webpage.
I wouldn't try this unless you have some PCB soldering expierience. I did the guages in about 1.5 hours (Watching ESPN Sunday night football)
