The former pressure switches contain ms connectors. The new pressure switches contain DT connectors. On the wiring harness, you must replace the ms connector with a DT connector.Use the following procedure in order to update your machine to the new DT connectors.Note: When you replace the ms connectors, disconnect the electrical connector to the pressure switch. Identify the pin that connects to each wire. The wire connections for the wires may not be obvious because the wires are potted. In order to reduce the opportunity for an error, cut one wire at a time. Perform a continuity check on the cut wire and the pin in the ms connector. Insert one wire at a time into the new DT connector.
