Thanks a lot. It's easy now. Wanted to do it long ago as DIY, as electrician starts playing tug of war with stuff, which might cause more troubles in future than I can count.
Will replace bulbs with leds and also clean it (small amount of dirt is there).
I am specifically doing it for temperature gauge needle, as that is not clearly visible, otherwise i avoid unwanted cher char and alterations of stuff that is working ok.
Just wanted to switch to multiflow system basically. More cooling and less engine load and better fuel efficiency, so fuel savings are contributing towards the amount i paid for multiflow setup.
