Thank you for your reply. It's effectively the driver's seat on the right. I do agree that removing the wall of the kitchen must not be a small task. I'm gonna check if I could possibly try to run a wire from the rear parking light to the back clearance lights harness??
Is that the driver's seat to the right? If so, the area of the wire splice would be to the left of the cabinet. I would check everywhere else before going into the wall, as it was not easy to get into.
