GlowShift 16 Pulse Speedometer Sensor Adapter Compatible with GM & Mopar Transmissions - Converts Transmission Mechanical Signal to Electronic for Aftermarket Speedometer Gauge

Perfect ! Fit right, worked well, did what it was supposed to.

Fit like a glove great product would recommend

When I replaced my 4-speed trans to a 5-speed, the speedometer would work for awhile and then drop and fluctuate near half speed. I bought this pulse generator and swopped it out and all works as it should without changing the harness. Simple install and works well.

Perfect fit for my 1979 Dodge truck. Quick install.

Worked great to run my new ( different brand) speedo guage. Comes with nice weatherpack plug/harness, enough wire to route through firewall to guage harness. Very pleased with purchase!

I bought this bc I wanted new gauges for my 79 trans am that I have a TH400 trans in. So I needed to convert it from cable to electronic for the speedometer and this worked great. Mainly bc all my gauges are glow shift along with this adapter so all the wires are color coated and with instructions telling you which wire goes to what it’s very hard to mess up. So I would highly recommend this product for anyone going from cable gauges to electronic.

Did not interface with OBD1 GM. Item is well designed, cable length is generous. Intended to replace speedometer mounted VSS. Which apparently uses cable driven led excited reflection sensor.

For what it does and for the price its a great deal
