Hi there new to the group here. I have a 2006 montana that has a dvd system single cd and radio no steering wheel audio controls I went to our nearest pick and pull auto wrecker and took the clock spring and steering wheel with audio controls from off a Buick minivan I changed it all over and there's no power to the audio controls what do I all have to change or do to get them working?

 

It's likely that the steering column wiring harness is different between optional audio controls and no audio controls. Similarly, options like with or without cruise control need different harnesses. You might try going back to the auto wrecker and see if the rest of the wiring is still in that steering column, and take pictures of where it connects under the dash as it's likely you'll need those wires leading to the stereo as well.
