AutoMeter Wire Harness Tachometer For Model 8199-05702

Add this optional wiring harness to our ultra lightweight carbon fiber racing tach model 8199-05702 to enable the ability to interpret a digital RPM signal (which is common to most conventional performance ignition systems and ECU) instead of the NASCAR McLaren ECU CANbus which the tachometer is set up for by default.
Legal only for use in competition vehicles which may never be registered, licensed, and/or used on public streets or highways; and also for use in other exempted vehicles.
