Hello
I'll install a new distributor on my 351W, do not know which one right now.
Thinking about the MSD 8354.

My tach is now jumping around and does not show me a correct signal.
The signal is taken from the MSD6AL through a MSD Tach Adapter PN8920.

Now I found this in the discription from the the 8354
RPM LIMIT AND TACHOMETER INFORMATION
Tach Signal: The Ready-to-Run Distributor features a Gray Tach Output wire which provides a clean signal for most tachometers and even some aftermarket fuel injection systems. The signal output is a 12 volt square wave, 20° duty cycle. This wire is also responsible for programming the built-in rev limiter.

Should this be the sollution for my application?
