ON the ScanGauge II's it says it can read air intake temps, does '98 have that sensor stock? I know stupid question but very new to 6.5TD's. If it does man that will mean I just need to buy separare gauge for that down road since I am buying ScanGauge soon anyhow.

IAT sensor is in the upper plenum....

Cool then the ScanGuage will work at my IAT gauge.
