Hi Guys,

I need to rewire the passenger head light on the 83 380 EURO SEC. Because what is there is such a mystery, I want to run new wires out of the fuse box. Basically the relays are a mystery to me, as is the very complicated light switch in the cabin. I would like just to run the wires from the fuse over to the light and splice it in. The car has fog lights, but they run directly out of the headlight "box" so they are not a problem. The issue is which relay contiols which light. The fuse box diagram does not say.

the swithch has thirteen wires coming from it, some of which belong to the hydraulic suspension system. I will need a diagram for this I am afraid
The light box has four wires coming into it. One brown, the ground, one white, probably the hot, one yellow, that is a mystery, and one green that kind of disappers in the light box, probably another ground

Any help appreciated.

By the way, I would remove the battery and the battery tray and clean out the mess. In my case, mice had built a nest under the battery tray in both cars. Also, tons of leaves had accumulated there and under the brke fluid resevoir. These cars have more nooks and cranies than an english muffin.
