1974 duster starting issue

Only starts when holding the key in start position for 5-10 seconds. There is no crank during this time. I do hear an electrical noise or click when I turn key. Also noticed that the radio doesn’t come on when key is in accessory/run position. When car is running the radio keeps turning on and off. Don’t know if that has anything to do with it not cranking. The neutral safety switch is new. Battery is good. Starter relay is new. Ballast is new. Car will start when bypassing the terminals on relay every time. I’m thinking something wrong with key switch. Is that behind the steering wheel?
(wanted to know before pulling wheel off). Been scratching my head for couple of weeks now. Checked ground and all wires to bulkhead. I’ve had this car since 1999 and this my first electrical issue. Any suggestions helpful. Thanks in advanced.
