The clockspring is the coiled ribbon cable behind the steering wheel that carries power to the airbag, horn and steering-wheel buttons while the wheel turns. When it wears out on a JK you lose the horn or cruise buttons and get an airbag light. Mopar 68339336AB is the current upgraded number that supersedes the 68193280 series.
Fitment
<strong>Year coverage is unresolved across sources.</strong> Mopar's eStore titles 68339336AB "Clock Spring 2007-2017", while a dealer catalog lists it for 2011–2016 and shows 5156106AG for 2018 JKs. The Dorman 525-127 covers 2007–2017 Wrangler and 2018 JK. Match the number on your old clockspring or check by VIN. Always confirm the number on your old part or run your VIN at a Mopar parts counter before you order.
Common failure symptoms
- Airbag (SRS) warning light on

Rebuild, repair or replace?
Replace, don't repair. Clocksprings are sealed assemblies. This part sits in the airbag circuit, so disconnect the battery and follow the service manual's wait time before touching the steering wheel. Center the steering and the clockspring before installation. An off-center clockspring can tear on the first full lock turn. On many JKs the clockspring is part of the steering column control module, so buy by matching the part on your Jeep rather than by year alone.
FAQ
Why does my horn not work and the airbag light is on?
Both run through the clockspring, so one failed ribbon can cause both.

Dorman lists the Mopar 68339336AB among its OE cross-references for JK applications.
