When i turn the key no lights come on on dash, dont hear fuel pump engage, turn to ign and wont crank. New stereo and ignition lock and battery

 

If you put a test light or VOM across the battery does it register?
Does the horn work?
If you jump across the starter solenoid (+ terminal to small wire) does it crank?
It sounds like no power is getting to the ignition switch.

What year truck? We need to know that to get further into the root cause(s).
