Tach codes for TAMD73P

[KalaKai]

I'm replacing one of my tachometers on a TAMD73P engine. The tach requires I enter a code, but does not include my engine model on the list in the box.

Any idea what the code is, or how to find out what it is?

thanks!

Thanks. I had that info and tried those codes without success. I sent the tach back and will try another.
