Forget using the schematic in the Haynes manual, or the one posted on the RN website, or in their old paper parts catalog. Those schematics are for NON US trucks.
The use of the green wire with yellow tracer indicates ANY of three mods specific to US Trucks.
Here is the Correct schematic for the US version of the S3. It includes the heater blower and the hazard light switch.You may have to resize it to read it.
BTW all series blowers are single speed motors. The method used to make them run 2 speed was to use a dropping resistor, located in the blower airpath, for low speed. High speed bypassed the resistor.
