Hazard light system

[mdl90]

Hi,

I would like to install a hazard light system integrated on the dashboard (like below)

I got the hazard switch "cavis" and an additional flashing relay 4 pins.

On my car, there are 2 originals red wires not connected behind the dashboard, one for the radio and the other for power supply to a hazard switch or relay ?

Has anyone added this system ? Or an original wiring on his car ?

It'd be a big help

Thank you,
