Twingo RS oil and water temperature meter

[H0L1]

I have a Twingo RS from 2008, I want to use it on trackdays but first, i would like to see the temperatures..... is there anyone who attached oil and water temperature meter to the sides of the tachometer? How did u guys do it, and where did you connect the electronics?

If U retro fit RS Monitor (not sure if possilbe for 2008 MY), it shows the water temperature. The oil temperature as well, but since there is no oil temperature HW sensor, it is only calculated somehow.

Easiest way I guess would be via some OBD reader and app, at least for water.
