This camera doesn't come with instructions but there is a good video on youtube about removing and refitting all the panels to route the cable. https://www.youtube.com/watch?v=AUoW6bCRQME. However the video is from the US and they routed the cable down the driver's (left) side of the car, also they are fitting it to a soft top. I fitted mine to a right hand drive RF (hard top) and I found it impossible to get the cable through the left hand side behind the passenger seat. Eventually by probing with a long wire I found a gap behind the drivers seat so I routed the cable through there. I'm not a mechanic by any means but I watched the video a couple of times and it gave me the confidence to fit it myself. The camera works perfectly and for giving that extra bit of reassurance when reversing I think it's great value for money.
