Neither of the front turn/park lights is plug and play on any of the "Euro" headlights. On the early style there is a plug receptacle but it is not wired for the front turn park lights. I tapped into city the light wire, side turn signal wire and ground wire. I used some round female plugs from a parts car to wire the plug receptacle. On the vacuum adjust lights you have to cut the plug off and splice into the proper wires. That is what was done on my '84 500SL.
