No wiring information is ever guaranteed. Colors and locations change with trim, options and build date, and the manufacturer can change them in the middle of a model year. We share this as a starting point for installers, and you are responsible for confirming every connection on the truck in front of you.
This page covers the 2006 Chevrolet Colorado and GMC Canyon. The Colorado and Canyon share the same wiring.
The colors on this page come from an installer sheet for a 2006 Colorado, matched to the other sources for this generation. Our own team has not yet metered these on a 2006 truck, and each row says so.
