Good To Know

Q: Does this tether switch work with all Ski-Doo models? A: It is designed for models that use the 515178286 DESS cap; verify compatibility with your year and model before purchase.

Q: Do I need to reprogram the DESS system after installing this cap? A: No, the cap physically attaches the lanyard; the DESS module is separate and typically does not require reprogramming for the tether function.
