Wiring Voltmeter w/ Key Ignition on M365 Clone (Monorim T2S Pro)

Hi all!

I want to add this voltmeter w/ key ignition on my Xiaomi Clone and I need to wire it so it reads the correct voltage (48V) and the key function will work


This is my controller diagram


What I have in mind is I will create a parallel connection in my battery to connect the black and red wire of the voltmeter but that will cause to the voltmeter to turn on indefinitly and deplete my battery (not sure) and where would I connect the third wire so that the power will only come to the dashboard once I turn the key on?

Any help is appreciated.

The power should be going to the key switch. Once on it would power the voltmeter and turn on the bike.

No one like full power going to the handle bars. I run 72v it would not be good for me.
