2000 Cadillac EL Dorado Won't start but has a NEW starter I

Electrical problem
2000 Cadillac El Dorado V8 Front Wheel Drive Automatic

I replaced the starter and followed the purple wire to the ignition relay and by-past it to make sure that the starter works and it started the car. While turning the ignition on to see if the relay would react but, nothing happened. I took the relay apart and theres no electrical burns nor are the contacts stuck.
So, is it the ignition in the steering column and if so, do you have diagrams and /or pics I can learn to remove the steering column?
