Is there a diagram out there which labels each of the spades on the ignition switch?  One of ours has nothing on it and we are curious as to what it is for.
Also, a question needing advice.  We were driving today and realized (viewing the new gauge) that the engine temps were climbing.  Stopped and cooled down.  The fan is not coming on.  Now headlights are also not coming on.  Changed fuses, all fine.  Headlight switch is okay.  
Ideas?
