1929 Speedometer Cable Routing

[RyanB]

As I am working through the final wiring and instrument hookup of my 1929 coupe I can't figure out where the speedo cable routes and where the clip mounts to. I have an unrestored cabriolet of my grandfathers that I am using as a reference for a lot of things but the cable is being routed out of the electrical junction box and I don't think that is correct.
