2011 GMC Sierra 1500 Wiring Harnesses

Genuine GM wiring harnesses for the 2011 GMC Sierra 1500, at wholesale prices. Harnesses carry the exact connectors and pinouts the modules expect, and they change with option content and build date. GMT900 through 2013, K2XX from 2014 to 2018, and the T1XX from 2019 with the CarbonPro bed option.

When you need them

Rodent damage, corrosion at a connector, or a repair after collision work. On a light duty pickup, cab configuration, drivetrain and box length all split this group, so the badge on the tailgate is not enough to order from.

Buying OEM, briefly

• GM stands behind it. The wiring harnesses warranty comes from the manufacturer, not from us.
• Priced below the dealer. Wiring Harnesses at up to 40 percent off list, with no membership.
• 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.

Getting the right part

Original tooling means original fit, which matters most on anything that has to align with a neighboring part. Our VIN lookup is more accurate than any public catalog. Use it before you check out. In stock orders placed by 3pm Central ship the same business day from our Dallas warehouse.
