My golf doesn't have heated seats installed but where the blanks should be under the centre vents a previuos owner has fitted oem heated seat switches which i do prefer to the blanks so earlier today i had the idea that i would like them to illuminate with the rest of the switches,so am i right in thinking that i can use pin 1 on the switches and connect these to the blue/gray wire on the dimmer switch? or will i need to do anything else?
