Nick, excellent write up. I will probably get the parts this weekend and tackle this in a week or two. I can vision mostly everything but would appreciate just a picture of the connections at the relay. Can you use a standard automotive relay?
Any chance you remember the part # for the relay at RadioShack? Again.. this is where my electrical knowledge goes out the door

.
Ill finally have a usage for some of the switch blanks on my center console now..

.
Is this the right type of LED you were talking about?

Again, please forgive my ignorance in this area.
