Hardline Tach on 2021 Superjet

Folks,
I searched this topic and still confused as to why I can’t get this tach to work. It’s the Hardline brand that I’m replacing a shred meter vibration style sensor. Mainly looking to keep track of hours for maintenance etc. I have wired this Hardline tech up twice with zero results. Anyone have pictures of how you are wiring the 4 stroke and what settings need to be changed on the unit itself. All content on line is not helpful.

Thank you in advance for the support!
