JDM tachometer installation - Toyota Celica, 1.8 L, 2000

After buying a car I wanted to put extra. tachometer. By chance I found a 110 mm JDM tachometer in the city. Reshino was to be taken. A few days later we went to the garage to put it. The salon sorted out easily, the tachometer was also screwed on without problems. There was only one small problem: what wire should I hook it to? They found that wire by typing. Collected salon. We start. Che is the weather on Mars shows ... Strange ... Look, it turns out the toggle switch is on 8 cylinders, we switch it to 4 cylinders and ... it works. Hooray :)
