Just be sure to put the input voltage to the input side of the instrument fuse. I believe that is the side opposite from the fuse block screw. That way your circuit is still protected by the instrument fuse.
As I mentioned, when I did this, my instrument lights were still too dim for me. I even jumpered a ground to one of the attaching screws. Still no good! It could still be the ground connection from the circuit board to the frame but I won't know until I pull the dash. I'll do that once the LEDs arrive.
