Will this work with my steering column without modification?

Yes—this mounts directly at the factory stalk position. No drilling, no bracket work. Install takes minutes with basic hand tools.

Do I need to splice into the existing wiring harness?

No splicing needed. The switch connects to your factory connector the same way the original did. Plug and play.

What if the switch doesn't work after installation?

Test the stalk action first—it should click left and right with smooth detent. If no signal lights, check your fuse and bulbs before assuming a switch fault. Contact support with your vehicle info if issues persist.
