ok i just read through 16 pages about clusters and came up empty. i want to change the lighting of the cluster...the info i need is what size led do i solder into my cluster??? 5mm??

I dunno about a 00+ cluster for the Cavi, I assume it is the same. But for the fire, you need to know how to de-solder and solder new bulbs or leds to change to color, not to mention take the whole thing apart to get to the board. It can be done, it has been, but you need to really know what you are doing. If you want you can always contact Alex at BlackCatCustom and have him make you an overlay, bulb or LED conversion. You can send him your cluster or have him get one for you. Give him a call if you want and set something up. Its always an option.
