Review on 🔌 MSD 8920 Magnetic Pickup Tachometer Adapter: Enhanced Precision in Sleek Black Design by Rusty Smith

Bought to work with my 1990 VW Corrado. I wanted to keep the standard tachometer and thanks to that I could! I'm going to do a thorough review of this as I'm very impressed with it. The tachometer signal is a square wave. Still, the touch has never been so clear. The standard VW speedometer driver twitches/twitches a little. I am using a Megasquirt pro-3 on my swap and I connected the speedometer wire from the control box to the input (white wire) and the purple to the standard speedometer wire. Another for power (red) and ground (black). It's literally that easy! I will be buying one for my next exchange as it will also be self contained.
