You shouldnt have a blown light display on your dash but if you do just wire in a 1ohm 1watt resistor to the + end and you'll be fine.
Stock mountings for the ballast are in the wheel well. If your wires arent long enough just shove them in the space underneath your headlights reserved for the headlight cleaner... but then again if you have the cleaners you could mount them to the back of the headlight unit itself.
