If you would like I can do all the changes you want done to them, you would have to send them to me though.
There are currently no LED's behind the gauges, it has bulbs I am converting over my gauges to LED as soon as I get my LED's in and I will be making a picture tutorial on how to do this if you would care to wait. as for switching over the door led's ther are several how-to's on this try this
How-to for doing this mod to the Cougar, the only difference is the master control on the drivers door on the contiques, there is a little piece that can pop out even if you are careful if you have problems with that I can show you pics of how it is supposed to sit correctly. Dome lights are going to be converted as well, I am changing them from bulb to a series of 5 or 6 led's, I haven't decided yet. PM me if you want any additional help or IM me on AIM - wstang455
