US emissions meant further differences between Euro and US cars, and even different wire colors get used on Euro and US cars. As electrical systems are a reliability problem. Knowledge is essential and an accurate diagram is mandatory. Owners add alarms and otherwise modify the electrical system and a return to original is often called for to correct mysterious symptoms.
