Headlights are easy on German vehicles.

Everywhere on the vehicle grounds are brown wires. Brown is the color of earth (possibly not in Oklahoma)

The low beam wire is yellow

The high beam wire is white.

Think white hot. Think dim (yellow)

Lots of times the hot wire to the hi-low switch is yellow with white stripe ... get it?

There are two separate ways the tail light is turned on
1 via the "city lights" position on ignition switch (you can remove key)
2 via the headlight relay when ignition is to run position (you cannot remove key)

the relay prevents back talk from the park circuit to the headlight in city lights ignition switch position
