2010 Chevrolet Colorado Wiring Harnesses

Genuine GM wiring harnesses for the 2010 Chevrolet Colorado, at wholesale prices. Harnesses carry the exact connectors and pinouts the modules expect, and they change with option content and build date. GMT355 through 2012, the 31XX mid-size from 2015 to 2022, and a new generation from 2023. There were no 2013 or 2014 model years.

Symptoms to look for

Rodent damage, corrosion at a connector, or a repair after collision work. On a mid-size pickup, box length and cab style drive more part number splits here than the engine does.

What you get ordering from us

• Factory sourced. These wiring harnesses are built to GM's own drawing by the supplier GM contracted.
• No guessing. Our VIN lookup resolves the near-identical wiring harnesses numbers for you.
• Ships from Dallas. Wiring Harnesses ordered by 3pm Central go out the same business day.
• Straightforward returns. No restocking games on wiring harnesses that did not fit.

Ordering correctly

Aftermarket versions are often close enough to install and far enough off to cause a repeat repair. Option packages divide this catalog more than model years do. Send the VIN and skip the problem. Our Dallas location means most of the country is inside a two or three day ground window.
