I did one installation, everything is working except coolant temperature gauge on instrument cluster.

Have you done the obvious and looked at the wire colour coming from the coolant temp sensor? It might be tied to the one that goes to the dash as well.

Yes, i looked that. Ecu send some signal to dash, but i don't know what signal and on what wire.

as i rememer some hondas want pwm signal for water temp, and that can be configured in vems many gauge output, which can provide pwm based on map or clt
