Will this require any wiring modifications to my vehicle?

This switch is designed to work with factory GM wiring harnesses. You should verify connector compatibility with your specific vehicle before installation to ensure a direct plug-and-play fit.

Does this come with the steering wheel pad or horn pad?

The switch assembly only includes the turn signal mechanism itself. You'll reuse your existing steering wheel and horn pad during installation.

Can I install this myself, or do I need to remove the steering column?

Column removal is typically required to access and swap the switch. If you're uncomfortable with this level of disassembly, have a shop handle it—steering column work involves airbag systems on many GM vehicles.
