Hi
I'm having trouble fully understanding the wiring diagram for the heated seat switches on the TIS.
The one wire I can't trace and don't know where it goes is the Grey/Blue that goes from the Passenger Heat Control Switch to "413-00-00-03" - My hunch is that it must be for the illumination of the switches but I'm only guessing.
I don't know what this is, can anyone please enlighten me?
also, what are the various number/letters (eg C309, S121, S3, C198 etc etc) please?
Finally, there appears to be no relay in this setup, is this correct?
many thanks
Grey/Blue wire's are nearly always illumination on VW's, just like brown wires are normally ground.
413-00-00-03 is the diagram is will appear on, normally you can click the number to be taken to that diagram and you'll find a corresponding coloured wire with a link back to the diagram number you've just been on.
C numbers are connectors, S numbers are electrical spurs (joints).
