[Mittie Lee 1935]

I Recently bought a 3 position Nu rex. Ignition switch that resembles the original but this one does not popout. My 1931 Ford has a single yellow wire that was attached to the original switch. I do not plan to use the Acc terminal on new switch. I hooked up yellow switch from my terminal box to the coil terminal and when motor wouldn’t start I hooked it to Batt terminal and car still would not start. Help, what am I doing wrong? I did buy a replacement cable that would run to the distributor from new switch and it has a black wire.Do I have to use this cable and if so where does the black wire go? If I don’t have to use metal cable does screw in at distributor have tobeplugged to keep moisture out?
