This is a genuine Mopar part — the same harness Chrysler, Dodge, Jeep, Ram, and Fiat dealers stock and install at the factory. It carries the original OEM part number, uses factory-spec connectors and wire gauge, and won't require pin swapping or adapter pigtails the way aftermarket alternatives sometimes do.

Yes. Genuine Mopar parts are considered OE-equivalent under the Magnuson-Moss Warranty Act, so installing this harness will not void your existing factory or CPO warranty. Aftermarket harnesses from brands like Dorman may introduce fitment uncertainty that complicates warranty claims at the dealer.

Stellantis uses alpha suffixes to denote engineering revisions. Later revisions (AB, AC, etc.) typically incorporate running production changes and supersede earlier versions — meaning AB replaces AA and is the correct current part to order. Always match by VIN at the dealer or use AutoBuffy's year/make/model/VIN lookup to confirm the active suffix for your specific build date.

For minor damage (a single chafed wire or burned pin), a professional splice using OEM-spec butt connectors and heat-shrink can work. However, Mopar recommends full harness replacement when corrosion, rodent damage, or collision damage affects multiple circuits. A full Mopar harness replacement eliminates continuity guesswork and restores factory water-sealing at every connector — critical in chassis zones exposed to weather or road spray.
