I bought headlamps for the fiat idea 2004 that turn out to be the ones that include foglamps. My Idea (Dynamique) has the standard headlamps = same unit but without foglamps installed. The car does not have the fog lamp button installed in the dashboard. Question: is the wiring the same/ is the wiring already prepared for the foglight option? What do I need to install the Foglight headlamp units?
