How does this gauge hook to  the block.. wire connection to the sending unit on the block with a nut and bolt or a sending unit mold on the end or a wire that screws to the block...?

Asked by: Butch”E”
Thank you for your question. It will come with our #2258 temp sensor that you will install then you will run wires from the sensor to the gauge. It does not use a capillary tubing.
