Painless GEN IV Tachometer Driver

This small device converts the 5 Volt 58X crank sensor signal from any Gen IV GM V8 engine into a 12 Volt signal usuable by most aftermarket and OEM tachometers.

Four wire connections to your vehicle and a simple calibration to run through will get your new tachometer up and running.
