I have a 1986 911 that I am putting back together. It had a cellphone wired into it. I am trying to remove it and trying to find out where the wire they removed from the fuse box goes back in to it? I have searched the wire diagram and cannot locate it. Appears to come out of the main wire harness. Medium weight red with a white tracer. I have attached photos of the wire and my fuse box. Please help.
