LS Tach signal, the proper way with best results. Part 2

This video is the follow up to the previous that revealed the tach was bad. Here we use a potentiometer to get proper resistance for the tach and you.

The tool is a clamping plier for squeezing tight certain clamps

Hey I’m looking at ordering a potentiometer on Amazon it has 3 wires coming off of it. Red, White and Black. Red would be 12v which wire would be for the tach itself White or Black?

I Have msd 6al-2 and tach adapter feeding original 70 falcon tacho and its about 35% low, could this same mod correct my issue 🤔

Hi what kind of resistor you use?

[@frotosgarage6715]

The resistor I use for this application with a relatively cheap SunPro 3" tachometer is a 4.7k ohm. Color code is yellow, purple, black brown,brown. Actual resistance on this specific resistor was 4.713k ohms. It seemed to do the best for a smooth transition as engine rpm increased and decreased.
