2014 Chevrolet Impala Wiring Harnesses

Genuine GM wiring harnesses for the 2014 Chevrolet Impala, at wholesale prices. Harnesses carry the exact connectors and pinouts the modules expect, and they change with option content and build date. W-body through 2013 and the Epsilon II from 2014 to 2020.

When to replace

Rodent damage, corrosion at a connector, or a repair after collision work. On a full-size car, trim level changes brake sizing, suspension and cooling parts within one model year.

What you get ordering from us

• Genuine GM only. Every wiring harnesses listing carries the original factory part number.
• Fitment checked by a person. Send the VIN and we verify the wiring harnesses before the box leaves.
• Central shipping origin. Dallas keeps wiring harnesses transit times short nationwide.
• Backed after the sale. If your wiring harnesses does not work out, we make it right.

Avoiding the wrong part

The cheapest version of a part is rarely the cheapest repair once labor is counted twice. The VIN decodes the build sheet, which is the only place option content is recorded reliably. We hold deep stock, so same day dispatch is the norm rather than the exception.
