Yup that’s me. If you do a search you should find it. I replaced all the bulbs with LEDs. Not easy to do and very costly. I posted directions somewhere. The only think I didn’t mess with is the climate control screen. I wasn’t sure how to do it and I don’t want to damage a $1,000.00 unit. Let me know if you need help.

This is ALL the info. There arent any specific bulb numbers for the climate control. You have to use regular LEDs and modify the factory bulb socket. If you take one out and look at it you’ll understand better. You have to wrap the LED leads around the socket so when you snap the socket in place the leads make contact with the board. You also have to solder a resistor on the positive LED lead (anode). I listed all the parts you need below.

This is NOT easy to explain but I'll try. I still havent found a way to change the climate control display or the clock YET. I will keep you posted. The bulbs that light up the cluster are just LED based 194/168 bulbs. You can get those from autolites.net or LEDtronics.com. (The LEDtronics ones are much better) There are 5 of those. You also have to change the bulbs on top of the cluster that light up the needles to LEDs. You can also change the
blinker bulbs. The climate control and switches are hard to do. You have to modify the factory clip that holds the bulb to hold LEDs. Its pretty annoying to do. BTW, use 1/4 watt 470 ohm resistors on all these LEDs.

Cluster:
5 194/168 based LEDs (Numbers)
2 5mm LEDs (Needles)
2 74 based LEDs (Blinkers)

Climate Control
4 5mm LEDs
2 3mm LEDs

Ashtray
1 74 based LED

Cig. Lighter
1 74 based LED

Shifter plate
You can use 1 74 based LED but it doesnt light up the hole thing. I modified a 74 based socket like the ones the blinker bulbs use and mounted a 5mm LED in there. It works much better but its up to you. If you get a 74 based LED all you have to do is plug it in.

Mirror switch
1 3mm LED

Dimmer switch
1 3mm LED

Cruise Control
2 3mm LEDs

Fog light switch
2 3mm LEDs

Sites for parts:
LEDtronics.com
3mm LEDs - Part No. L121CB1K-3.5Vf ($6.00 x8) (UNDER DISCRETE LEDs)
5mm LEDs - Part No. L201CB1K-3.5Vf ($8.00 x6 or x7)* (UNDER DISCRETE LEDs)
74 based LED - Part No. WF150-0PB-014V ($9.50 x4 or x5)*

*This depends on how you plan on doing the shift plate. You can use either LED but the
5mm needs to be modified.

Autolites.net
3 packs of 194/168 blue LEDs ($16.50 x 3)

Good luck! I would order a few extra LEDs. I managed to blow 1 out by accident so be careful.

The 194 bulbs come in 2 different types. One comes with 1 large LED and another comes with 6 smaller LEDs. The one that comes with 6 is better but costs $22.50 each. I PMed you about the cluster. Do this at your own risk. You might damage somthing if you dont do it right.

I used the 1 large LED style bulbs. They are kind of dim though and don’t shine through too much. I replaced the 2 bulbs that light up the needles on top of the cluster with two of the
LEDtronics 5mm LEDs. Now the cluster is real bright from the outside. The 6 LED would work better behind the cluster but you’d have to spend $110 just for 5. I don’t think its worth it.
Superwhite LEDs would be brighter than blue.

They’re really aren’t any tips for taking out the climate besides “just take it slow and be careful”. If for some reason you need to take the whole PC board out of the climate it has a few philips screws and you must take off the temperature knob which just pulls off from the outside. Good luck. If you need help (I’m sure you will) just post again.

Dude, its not too complicated. The bulb socket is a twist and lock type socket. Its basically a plastic round circle with a groove that the bulb sits in. There are 2 little holes on the bottom of the socket for the leads coming out of the bulb to pass through. The leads then wrap around the sides of the socket so when the socket is locked in place on the board, they make contact. Once you get the bulb out and slide the LED in place, you'll have 2 long leads coming out of the bottom. Cut the power lead so thatl only a little bit shows, then solder a resistor on that. Now you'll have one lead from the LED (ground) and one lead from the resistor. Twist these around the socket the same way as it was done from the factory and snap the socket in place. Done! If it doesnt light up then you just need to take the socket out and snap it back in the other way. The polarity was just reversed. It wont damage the LED. Heres a pic I made that might help. Like I saidm if you see the actual socket you'll understand much better. Take out the climate and look for yourself. Its not hard to do.

it really isnt that difficult. once you actually look at the socket and see what it looks like, it will make sense. describing it can be the hardest part.

1 question though, in the directions, it shows you only need 2 LEDS for the speedo and for the tach. what about the fuel gauge? can you use anohter led for that?

:mad: Why is that guy using a picture of my climate control in his auction? I bet those whole instructions are the ones I posted on A-tl.com. I sat there and typed those instructions and reviewed them and now this guy is selling them. Not the mention I tore my car apart and a tried this all out. The idea all came from Austin and Nate but that was for 2nd gen TLs. It helped me get the concept of it but alot of stuff was different. He could've at LEAST used a different picture. OR he could've at least asked me first. Is that anyone from this board? Look at that ebay auction TLontheDL posted then go HERE and look at my first attachment.
