The tailight wiring comes from a separate pin on the headlight switch (because you must have the tailight on in the parking light position and in the headlight position). The pin is stamped "T" on the back of the switch but itsn't very easy to access (mirror ?). Try to remove the tailight wire (black wire) from the switch and look at your tailights. If they are off the switch has to been remove (not easy..)and replaced or repaired , if the lights are still on you've some shortcircuit between the switch and the lights. -- Philippe COURANT (Pau, France) Imperial 57 Crown convertible Buick 58 Roadmaster sedan - American Car Club de France (ACCF) : http://www.accf.com - Chrysler Imperial France : http://www.ifrance.com/c-i-f - Cadillac " Standard of Excellence " : http://www.ifrance.com/accf-cad - SportsCars : http://www.ifrance.com/accf-sprtcar
