Description
The Dakota Digital SGI-20 GMR Tach Adapter takes the guesswork out of tachometer signal conversion. It uses an advanced GMR (Giant Magnetoresistance) pickup to clamp directly onto a low-voltage, high-current wire, eliminating the need to splice, cut, or make any permanent modifications to the existing wiring harness.
Once installed, the SGI-20 converts the detected signal into a clean, stable 12-volt square wave output that modern instrumentation can reliably read. Whether retrofitting a classic hot rod, upgrading a custom build, or troubleshooting a signal compatibility issue in the shop, the SGI-20 delivers a consistent signal that gauges or engine management systems can trust.
