No Relays on this model Andy, models with daytime running lights have relays.
I have a wiring diagram now and the power is straight through the switch to the bulbs.
Car is at nissan now as they won't replace the switch under warranty until they've checked it, they are saying there are two types of switch and which did we fit? No idea I said, the one they supplied. No doubt this is going to bite me on the arse.
