Dude thanks so much!
I just added the whole instruction message to a thread, rather than you having to wait while I copy/paste this whole thing into 1000 characters per message... http://www.clubwrx.net/forums/interi...ml#post2497788
Hmm. I will start with the instrument cluster, and work my way out to your door switches. First, it is a resistor, you can experiment with them, but 2.2KOhm seems like the standard. You want to make sure that the resistor is soldered to the positive lead (typically the longer one on a raw LED, otherwise, using a 9v battery and terminals, test to see what leads are the positive on an aftermarket "dash kit" type LED. Don't test a raw LED with a battery, it'll burn out in seconds or less.
this is part one of many messages coming to you, i can only post so many characters at a time.
