Well, to be honest, it is not an impossible task but for sure not an easy one. The part of the harness that goes to the engine is really easy to remove, with fenders unmounted it's a 45 mins job. The real pain was that the harness is a one piece deal for the entire cabin; a plug on lower A pillars would have saved half a day or more as you have to remove every single wire from the cabin, including rear seatbelts, boot lid light, rear sunshade, rear lights etc. If I would do it again, would cut all the wires from the lower A pillar, buy a pair of universal plugs and attach those for easy removal. At this point, we managed to put the LHD loom inside the cabin , sort the mess between the wires that need to go on the driver's side and passenger side and we finally managed to plug everything to the rear of the car back. First days in the new year, we will sort out the plugs under the bonnet, mount everything back and then finish with the dashboard loom. We will record the first attempt to put the ignition ON and start the engine; camera man will have a fire extinguisher
