Total Racing Products Kill Switch Security Harness – R35 GTR

The Total Racing Products Kill Switch Security Harness is a stealthy, plug-and-play kill switch solution for the R35 GTR. Designed to disable engine starting functionality, this harness allows an existing, rarely-used OEM switch to act as a hidden security switch—no cutting, splicing, or interior visible modifications required.

When the switch is flipped, the harness prevents the car from cranking and starting up. Flip the switch back, and the vehicle returns to normal functionality. It’s a clean, OEM-integrated solution for added theft deterrence or immobilization, using components already built into the vehicle.

This harness uses weatherproof components and connects inline with existing OEM connectors, maintaining full factory integrity while adding a valuable layer of hidden protection. Installation is fast and frustration-free—each leg of the harness is clearly labeled, making it an easy guided install with no further instructions required.

Even in the event a car thief replaces or reprograms your ECU or BCM, this security harness will still prevent the vehicle from starting.

Key Features:

• Plug-and-play install with zero wire cutting

• Easy guided install with labeled connectors—no further instructions required

• Utilizes a factory OEM switch as the stealth kill trigger

• Prevents the vehicle from cranking and starting when activated

• Fully reversible and non-intrusive

• Compatible with all 2009–2024 Nissan R35 GTR models
