Today I went and changed my American style sealed beam headlight to the Euro H4/H1. To my delight I did not have to cut the connectors. I went to Bosch and told them what I needed to do and after almost an hour of looking the guy came out with 4 new headlights.

The low beam H4s plug directly into the old connectors.
The cover that comes with the high beam glass (to keep it water tight) comes with a connector to connect the H1 bulb to the old high beam connector.
