2010 Pontiac G3 Wiring Harnesses

Genuine GM wiring harnesses for the 2010 Pontiac G3, at wholesale prices. Harnesses carry the exact connectors and pinouts the modules expect, and they change with option content and build date. Rebadged Chevrolet Aveo hatchback sold in the brand's final years.

How you know

Rodent damage, corrosion at a connector, or a repair after collision work. On a compact car, option packages divide this group more than the model year 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.

Confirming fitment

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.
