just ordered the blackjack unit you recommended, along with the tips, some braid and some better tweezers. thanks for the recommendations Jeremy. much appreciated.

Correct, you need to de-solder all of the pins with a solder sucker and carefully remove the screen. If it is not done properly and if you pull on the screen at all with one of the leads attached it will crack and be useless. This is the #1 issue I see from diy customers. Just take your time and make sure each pin is free.
hmm I don't exactly get what you guys are saying here. anyways someone could get a picture or video to explain this better? I'm going to get started soon nd would like to not screw up

Re: How to remove / solder a PLCC LED for gauge / hvac work PICS
from the little experience i have doing it (only done 3 of them) you place the iron tip on one side on a pin and as the solder liquifes you butt the sucker up to the other side of the pin and suck it out. you may have to do it twice to get most of it out. try and keep everything close together to help create the suction effect. ever after sucking out the majority i still went over each pin with my iron and tweezers to make sure each pin was loose in its socket, just in case. i guess some people were trying to use copper braid to remove the old solder and the amount of heat they were sending thru the pins was cracking the screens. its not to hard, just take your time. hope this helps.

jeremy, any chance you would be willing to put a diagram on your site for swapping the leds and resistors in a basic scion headunit?
i ordered a green kit a few days ago to try and mod my wife's tc. also, on your store you sell the option for the tc gauge cluster resistor upgrade; is there a way i can buy the resistor kit to do the upgrade per your diagram? thanks for everything, all your write ups, parts and diagrams have been really helpful in modding my xd and tc.

Hello,
The diagram for the display led kit I sell is on the site, it is the same for all non color changing scion pioneer radios "except the new model premiums" As for the leds, not much to do for a diagram, I just open them up and change out every single led. Usually around 35-40 0603 sized units.
Not understanding the question on the gauge cluster resistor upgrade? Shoot me a PM anytime to discuss!

I'm about to get this done and really would like to order some but i don't want to order too much or too little. I'm going to be needing red, so do you happen to have any pictures that shows the difference between 1 layer and 2 layers of the red vinyl?

You will want 2 layers of red vinyl rather than 1. makes it more vivid so 2 sheets total. Each section of the hvac is lit individually so no vinyl is used on the hvac. Just pick the color leds you want.

yeah I got that 
I've been practicing on a spare cluster. i'm not great at it but I know i'll be able to get the job done :D I just have to be sure not to F up my gauge screen olike I did with the spare trying to put the red layers on how I want them.

So Back to the HVAC. I'm trying to desolder the screen and don't want to break it. I'm trying to use the solder sucker but it just isn't working well. the tips on the two different suckers i've tried aren't small enough so i can't get close enough to get the solder while its hot. any differen tips for me? I know you said not to use a desoldering braid but maybe its time for me to give it a try anyways?

You can try braid, but I definitely do not recommend it / I never use it. Sorry you are having trouble. Do not stay on any one pin for to long if you are having problems, move to another pin and keep working it.
