GlowShift’s 16 Pulse Electronic Speedometer Sensor Adapter for Ford Tremec converts your transmission from a mechanical speedometer signal to an electronic signal that sends electronic MPH readings to your GlowShift 3-3/4” In-Dash Speedometer Gauge. The installation process is easy, with this Ford electronic speedometer adapter taking the place of the factory speedometer cable connection. The speedometer sensor adapter’s 3 pin male connector plugs into the female connector of the 9’ wire harness that is also included. Additionally, the wire harness has 3 lead wires for sensor, power and ground connections. GlowShift includes installation instructions, free lifetime tech support and a one-year limited warranty with each speedometer sensor purchase.
