Wireless Temperature Sensor Pinout

I have a K-Type Thermocouple sensor that I would like to wirelessly transmit back to our NCD gateway. I would like to use the Wireless Thermocouple Temp Sensor to accomplish this.

I was thinking that I could buy one of the M12 connectors and wire our sensor directly into the module instead of using the thermocouple connector. Does anyone have the actual pinout for this connector?

I am also open to an alternative if there is a better way to accomplish this.

Thank you!
