Speed Can

Hello everyone.

I'm new here and I'm looking forward to your help .
And here's the problem:
I have a car (a Nissan) where the speedometer, tachometer, fuel gauge, and water temperature are all displayed normally without using a CAN bus; it's basically OBD II.
Jetzt habe ich mir einen Tacho gekauft der unbedingt ins auto soll, jedoch ich nicht gewusst habe das bei dem Drehzahl und Wasser Temperatur über Can Bus laufen.
I'm completely at a loss as to how to do this!

I would really appreciate it if you could help me get the speedometer working again.
If needed, I can also post wiring diagrams.
FastgateI can also gladly post circuit diagrams if needed.
