1969 S tail light wiring

Is there a specific route for the rear stop light wiring where it joins at the fairing without the cable showing David

Along the right side of the rear frame rail and then into the fairing between the rail and the fairing, not invisible. I fixed it with two or three cable ties along the route. You can route it under the frame rail- almost invisible. Cleanest version would be inside the frame rail which means to drill two holes for in and out, I can not recommend that for stability reasons. On my BMW R 75/5 it´s routed that way but the rails have a bigger diameter, but it is a PITA to get the cables through.
