Installing speedometer wire

[RRSweden]

I'm about to install the speedometer wire from my A833 on my 71 Road Runner.

I didnt find any explenation in the service manual about wich hole in the firewall it goes through...
And on the inside, behind the cluster I don't know how the wire's supposed to go... It bumps in to pedals, clutch-springs and what not...

Please help. Picture's are very helpful!

thanks

Well, I don't know how much help I can be BUT I am in the process right now installing the speed control unit and cables.
On my 73, the hole is almost directly under the power brake booster to the left (driver) side of the steering column and next to it is the brake release cable.
Pictured below, the old cable is painted red but you get an idea of where it is.

And in this picture Just left of the brake pedal but under the carpet. The one below that you can clearly see it.
