If anyone has done this and succeeded please chime in. From what i have read here on the forums here is what i will need.

Pedal
Cable
Idle Air Control Valve - Is this in the throttle body?
Throttle Position Sensor - Is this in the throttle body?
Cruise Control Module

What wiring will I need?

Allen informed me that I would have to change the gauge cluster.

I will be getting all the parts for my 04 Silverado from an 04 silverado.

Thanks for you help.
