tach install on a ski doo

Hello again. looking to install a tach on my 97 Ski Doo Touring E LT. trying to match the tach to the speedo, the speedo is smaller about 3 1/4" diameter and is black background with green numbers. I can`t find a matching one for my year, but going back to 93 it is a perfect match (it even looks like the plugs match). so will an early 90`s tach work on a late 90`s 380 sled? meaning will it read the proper RPM`s? I`de like to have a tach to make sure the engine is running where it needs to be and that the clutches are operating properly! not to mention balancing out the dash due to having no tach right now.

Thanks!
