Eliminating Seat Cutting: A Game Changer for NEXO Owners

Traditional wireless walk-in switch installations often necessitate cutting into the passenger seat's fabric and internal structure. This is typically done to conceal the sensor and wiring harness. However, this modification is permanent and can lead to complications during resale or repair, often raising questions about the seat's condition. Furthermore, compromised seat areas can become vulnerable to water ingress. The S-WALKIN wireless walk-in switch for the Hyundai NEXO addresses these concerns by adopting a fundamentally different approach. Its design prioritizes preserving the original seat while delivering the full functionality expected from such an upgrade.

The Plug-and-Play (Zick-by-Zick) Wiring System

What sets the S-WALKIN apart is its innovative "Zick-by-Zick" wiring technique, which essentially means a plug-and-play connection. Instead of splicing into existing wires, this method utilizes the vehicle's original connectors. The installation process is remarkably straightforward:

1. Fully extend the front passenger seat forward.
2. Locate the original IN/OUT cables beneath the seat.
3. Connect the S-WALKIN signal wires directly to these exposed cables using the provided connectors.
4. Secure the main ECU module under the seat using the included cable ties.

This system ensures that the factory wiring remains untouched. The module connects to the switch, with power, ground, and signal wires clearly color-coded for easy identification, making it accessible even for novice DIY installers.

DIY Installation: Achievable in Minutes

For experienced individuals, the official installation time is estimated between 8 to 12 minutes. First-time installers can expect to complete the process in approximately 15 to 20 minutes, with the slight difference often attributed to removing and reinstalling the passenger seat. The primary advantage of the DIY approach is the complete absence of installation costs. Moreover, since no permanent modifications are made, the original seat can be restored to its factory condition at any time, which is beneficial when selling the vehicle or if the owner decides to remove the upgrade later.

Professional Installation Option

For those who prefer professional assistance, installation services are available through certified dealers. The process typically takes 20 to 30 minutes and incurs a nominal fee of 15,000 Korean Won. Professional installation guarantees a secure and correct setup, with technicians verifying proper wiring and signal transmission. This option provides peace of mind, ensuring the upgrade is performed to the highest standards without any risk to the vehicle's electrical system or seat components.
