There is a technical bulletin issued by Nissan where it is described what dealer needs to reconfigure so that you won't get false alarm when towbar is attached (if you use detachable towbar). If there is also trailer attached, there is no official way to disable rear parking sensors, unless you modify the system.

Nothing between 10-13

In the boot the following photos show
1) Power to perm +ve but no power to fridge wire
2) Bridged Perm +ve to fridge wire. Lights in caravan lights went out and fridge worked. This is correct and proves that the caravan habitation relay is working and hence the fault is in the car
3) connecting a cable from the rear to the battery fuse and testing resistance gives resistance so the fault is between the battery and and rear connector.

The cable from the battery is routed into passenger side and across to drivers side into a connector and fuse box then back to passenger side to go back to the boot.

I have checked the earth for pins 3, 11 and 13 - all fine.
The fridge wire does go to pin 10.

Two wires come from the vehicle +ve battery via fuses to the passenger side compartment, one red and the other red/yellow.

The red one carries to the boot and is the permanent +ve to pin 9 on the 13 pin socket. This is correct.

The red/yellow wire again enters the passenger side, where it is live, and travels to beside a fuse box at the drivers side door. It then returns to the passenger side as a yellow wire and onto the boot to supply pin 10 (the caravan habitation relay and fridge). This should only be live when the engine is running.

The red/yellow wire from the +ve battery is live in the passenger side, but when it returns from the drivers side as the yellow wire it has no voltage when the the engine is either on or off.

Therefore the fault lies between the red/yellow wire from the passenger side and yellow wire returning returning from the drivers side.

From this I am assuming that the relay is on the drivers side beside the door beside the fuse box.
Is it possible that they forgot fuse?
