2017 Suzuki DF25ATHL2, I need tach pick up point

[Mainia]

2017 Suzuki DF25ATHL2. A tiller. From my initial research there is no tach pick up point on a tiller. Some say my only option is a Tiny Tach that picks up off of the plug wire, but they break all the time and their accuracy is in question.

I would like a 4 "real" tach if I could. Any ideas if there is a electrical harness end that I could pick up from? I was told tillers have NOTHING.

I don't have the motor yet, next 7 days from this post is when I am picking it up.

Thanks
