I have no idea where to get the six pin connector case except for the dealer. You will need a patient parts man. Follow Mikes instructions, don't "cut and splice."

The vast majority of the headlighting quality is due to reflector shape, not the bulb. Your headlighting will be DRASTICALLY improved with your Euro headlights. You will have absolutely no need for high wattage lights. The added current will eventually ruin your wiring and the added heat inside the headlight assemblies will ruin your expensive Euro lights.

Try the standard bulbs first and then start adjusting the lights. After they are adjusted, then if you STILL think you need brighter bulbs, use relays for the wiring, but still expect eventual headlight assembly damage from the added heat.

Enjoy,
