Download the zipfile below, which is the tutorial that Captain Morgan wrote up. Here are the following things that need to be cleared up though...All parts can be obtained at Radio Shack.
(7) Blue LED's #276-316
(2) 330 ohm 5-pack resistors #271-1315
(1) spool solder wick (braid) #64-2090
(1) spool solder #64-013
(1) roll electrical tape #64-2374
(1) Phillips head screwdriver
(1) Flat blade screwdriver
(1) Channel lock pliers
You need 9 LED bulbs (NOT 7 AS STATED ABOVE!) if you wish to do the HVAC and stereo. It's 7 bulbs for the stereo, 2 for the HVAC.
The pliers are not needed either, but may help. You will also need a razor blade, or exacto knife. You know the sort that comes with your average toolkit.
Anyway, I think his directions are pretty clear for the most part up though step 28... Once you hit step #29, he's not real clear IMO.
So use the tutorial for up till that point. If you have any questions though, feel free to ask.
Now here's where things get scary! Flip the board to the green side, where you do the soldering and all that fun stuff.
The positive connection on the circuit board needs to be literally cut! This is where you need the exacto-knife or razor. I'll add a second post with a picture I just did with PAINT to give you an idea of that. Find a nice spot to cut into the board which isn't super close to anything else you might cut. Now as the tutorial says, scrape away until the metal connection is gone.
Now, those those little black things all over the board are the SMT resistors. Solder one end to the positive line of the LED, and the older solder directly next to the SMT resistor which should already have a tiny bit of solder in that spot. The power will now transfer from the SMT resistor, to the 330ohm resistor, into the LED, safely going within the power limits. Sounds crazy, but it's to cut the original power voltage from reaching the LED and killing it's life span from immortal to quick death.
Now only the HVAC is left. I'll draw up another PAINT picture to give you an idea how to safely set those up.
OH, btw, for those of you who don't know (and I didn't when I started this project) the positive end of the LED is the longer end.
