Schematic 1988 S4  (US?)

1991 S4 ROW

1991 S4 (US version)

1993 GTS US version

the bulb controller has a 14 pin connector but there is a difference for US and ROW models:
The US has 14 wires connected where the ROW model has 12 wires connected.

Yes, Pin 11 and 13 both have an identical wire. If you want to be sure, you need to measure the resistance on the wires when one stop light bulb is removed. That will show you which is left (and right).


Pin 1 and 3 are not used in the ROW model, they are for the additional side marker lights in the US model.
