Well, the Colorado is much newer truck and comes with newer style e40 computer where the 2001 Silverado came with the older 411 style computer. From what I am finding so far, the Colorado's ECM interacts with the body control module (BCM) a lot different than the older trucks. Even the ignition is routed through the BCM. I am not worried about the mechanical aspect but more worried about the electrical part of it!
