Gas Tacho / Revcounter Conversion to Diesel W terminal

Do you need to modify the electronics on the board?  Or is that only apply to a gasser to diesel conversion?

I just ran across this youtube video. Apparently you can by a diesel tachometer for $23 on ebay. The video shows a vw mk2  with the gauge hooked up.  https://www.youtube.com/watch?v=XBhNItz8HAU

Went to Car Lab and could not find this tach anywhere.  I wonder if it is a gasser and not for a diesel.
