I have purchased a pair of Euro headlights for my 89 300e. The headlights have 5 pins in them, and the car has a 4 prong connector. I have searched throughout the forum for the proper wiring but came up empty handed. I have called my local Mercedes Benz dealer and they do not have a female 6 prong adapter for the headlights. Is there any other way i can wire the headlights. Can anyone explain how to make the proper connections from the 4 prong adapter to the 5 pins in the headlights??
