My Defender has some Disco2 seats in at present, both front and back that I am looking at swapping as they are tatty and I am not sure the back one is fitted safely. I am looking at the options, standard defender ( I have got a back seat now) , RX8 and so on and have heard people have fitted Range Rover P38 seats which I notice are available very cheaply in leather with the excellent front armrests. However they are all electric! Has anyone wired them in to an old Defender and was it hard? What's involved?
