I dont think my odo ever lit up (got car used), thats what sort of braught up this mod,I was taking it apart so see whats up, then got sidetracked to say the least. Then I decided to go for it, and I liked it, had 10 people ask me how I did it and then comes in this tutorial. I had to take it all apart again and take pics, so understandably some of the info may be a little bit off because it was sort of a re-run for me.
I tried the HVAC with one on each, not dark enough for my taste. I dont need light output unless its night, so I put two on, it looks good in the dark. Gerbs said he was having some difficulty with the 04-05 cluster, maybe different lamp placement, so ill try and sort it out with my lab gerbs for the new gen before anyone else tries this (new gen people might want to wait a bit before I sort this out with Gerbs)
Kenji, King Fish and others might want to hold off for a bit.
Also, Ill be on AIM from time to time, so if you have any specific questions just ask me, please no theoretical questions before you take it apart, but if your tried and are having trouble feel free to ask.
