Here is a step by step guide for LED Conversion/Swap

Things you'll need (Mostly available at RadioShack)
- Fine point Pencil Soldering Iron (Recommend 15-30 watt)
- Solder : Prefer silver-bearing solder or rosin core solder (Thinner the better, easier to work with)
- Soldering accesories
- Philips screw driver
- 10mm socket wrench or needle plier
- Surface mount LED, resistor and voltage regulator (Available at LEDmod.com)

*** NOTE : If you are doing Red LED conversion, you can skip the resistor and voltage regulator swap.
Just change all the LED to RED, also removing the LCD screen is a must

Schweeet!!

 

Impressive!!!

 

Nice! Looks a lot easier than I once thought. It kinda eases my mind knowing that those PLCCs are lot bigger than the 0603 LEDs like in the Wiimotes.

I know that SL has a tech article for the gauge cluster already, but I'd like to see a guide like this one for the gauge cluster.

 

I'll be making one for the gauge cluster soon....
After I'm done with the 07 and up model for climate control..
I have all the pictures, but need to spend time making them all nice and easy to understand....

 

So I got a quick question: I tentatively want my HVAC to be all white, with the on/off lights be red. Will doing the resistor swap harm those red LEDs in any way?

 

For the on/off LED, resistor mod won't effect them...

 

Excellent write up! Very professional.

Be careful removing the lcd. =) I cracked mine =( It's been broken for a very long time now. If anyone has a replacement, I'll buy it. Seriously.

 

Guide has been updated with 07+ Models

 

are the resistors plug and play or needs desolder and solder too?

 

You'll need to install them by using soldering iron..

 

When doing the LCD screen, how do you get the Reverse look to it?

Does that require a different screen, or do you just put it in backwards?

There is two way to do the reverse LCD..
Reversing the stock film and using new film that will reverse it(I sell them)
If you use the stock film, it's really hard to keep it clean. Since it's tidious to remove the film without bending and remove the adhesive...

When using new film, just clean up the adhesive after removing the stock film...
It's easy to remove the adhesive on the LCD screen it self... just apply some adhesive remover and scrape it off with sharp razor blade.....
Then put new film, it comes with self adhesive layer...

 

Is there a way to change the CD Player/ Head unit LCD to another color?

 

yes.

 

I'll probably make another guide on stock Radio LED conversion guide....

 

i really want this set up...but can't do it by myself!!

 

I highly recommend NOT useing solder braid, it is how 95% of the first time swappers crack their screens. Use a solder sucker and do it right. Also a writup on resistor placement & info has been up for 2 years now Pretty hard to make wheel more... round

Last, the power ic you are useing is only a 500ma unit, should be a 1amp rated unit minimum.

 

yep, u dont want the solder to drip down.

 

Noobs also put to much heat on the braid for far to long which damages the lcd screens. All around a long painfully annoying process to use solder braid which usually results in some sort of damage. I can desolder a screen in around 1 - 1.5 minutes with the equipment I have and I am not even in a hurry And non techies can do the same in a little more time with just a solder sucker & low wattage iron.
