AU Fairmont - No water temp signal to dash

[xr6tjet]

Hey guys,

Pushing through my barra conversion and there's one last issue I can't work out. The water temp is hooked up for the AU ecu, it's getting to the ecu as I can pull the temperature from the OBD2 feed however it is not operating on my cluster. Are there any reasons as to why this will not operate on the dash as I understand the ecu generates this signal? I also cannot work out why my aircon isn't working, it is all hooked up still as per factory. Would it make a difference if the ECU is getting an RPM signal or not (currently is not).

Cheers, Alex.
