This is the Trust SM Integrate 4-piece set. It is a boost, water temperature, and oil temperature control unit. Only the water temperature sensor is included, so please prepare an oil temperature sensor separately. There is only one wire to connect the meters in the photo, but if you need more, I can send you one that has been slightly extended. I think this is a rare item that is not often available. It was working normally before removal. Please judge the condition from the photos. This is a used item, so please understand that it is non-returnable, non-refundable, and non-cancellable (3N).
