I've got trusty old manual seats but I've considered getting electric ones. Does anyone know if the wiring loom exists for them in a car without them or has anyone else done the same?

i would immagine the relays will be integral to the seat, so it should only need a power supply. i havnt looked close but im sure there sreonly a couple of wires under my seat.

Cheers, that would open the possibility fo not just looking for non electric chairs.

check out the online wiring diagram, as this is just an assumption. it would make sense that Nissan would run a power cable to the seat and leave it redundant where electric seats are to be fitted, rather than fit a complete wiring loom to a car that had them fitted. and seeing that all the motors and switches are integral to the seat, i dont know what other wires you would need to run to the car.
