Rywire OBD1/OBD2 1992+ Main Relay Kill Switch Harness
The Rywire RY-RELAY-OBD1 Main Relay Kill Switch Harness is the best anti-theft and security upgrade for 1992+ OBD1/OBD2 Honda/Acura vehicles (and compatible 92+ platforms). This plug-and-play harness allows you to install a hidden kill switch that disables the main fuel pump relay, preventing the engine from starting without the proper key sequence – ideal for track cars, street builds, or anyone wanting simple, effective theft protection without complex alarms or ECU tuning.
Key Features

- Universal Compatibility: Works on most 1992+ Honda/Acura models with OBD1 or OBD2 main relay (Civic, Integra, Accord, Prelude, etc.)
- High-Quality Wiring: Rywire premium harness with weatherproof connectors and durable construction
- Simple Installation: Mount hidden toggle switch in a discreet location – no ECU or fuel system modifications
- Made in USA: Handcrafted by Rywire for reliability and clean fitment
