Can I hook up a Dwell/Tach Meter to a BF25 as a Temporary Tach?

[North Plains Drifter]

I have an old school Dwell/Tach meter that I use on my old cars, is it possible to use this as a temporary tach? I'm not sure if there is a way I can tap into it to make it work.

Upon further thinking not sure if it will because of the number of cylinders...

Any thoughts?
