1966 Chevy Truck installing a later model tilt steering col

1966 Chevy Truck V8 Two Wheel Drive Automatic

I have a 66 C10 that has had the wiring butchered. I got a wiring diagram from you. Once I started tracing things down I found the wiring in the steering column completely burnt. It is a later model column and was not hooked up correctly. I went to the local salvage yard and found a pristine tilt column out of a 78 C10. I thought $50 was a great deal. Is there a quick rundown on hooking up the hazard light switch to work that was not available on the 66? Or can you point me in the right direction?Thanks for your help
