Autometer Hall Effect Speedometer Sender Mechanical to Electric GM/Chrysler 7/8in-18 Thread 16 Pulse

This Hall effect sender from AutoMeter is built to take the mechanical speedometer drive from GM and Chrysler transmissions and convert it into an electronic signal. It's designed to thread directly into transmissions that originally accepted a 7/8" x 18 thread style speedometer cable. This is a really handy part if you're swapping in a newer transmission or adding an aftermarket electronic speedometer to a classic vehicle.

It outputs a 16 pulse per revolution signal, which is a standard 12-volt square wave that most modern electronic gauges can read. One of the neat features here is the pass-through connection. This means you can still connect your original mechanical speedometer cable, or more importantly, support other accessories like cruise control that might still need that mechanical link to the transmission. It's a well-built piece that makes integrating different systems much simpler.
