Magnum sensors compatible with analog digital dash gauges?

Do you know if the sensors on a 97 5.9 donor OBDII would be analog? I would like to connect the OIL/TEMP/VOLT gauges to a modern digital gauge panel. I’m guessing this year is pre Data-Bus, but does the ECM monitor the sensors for optimum performance?

-Speedo: using geared cable and sending a VSS signal to ECM
-fuel level: not a problem using a traditional sender
-OIL, TEMP, VOLT gauges: Unsure about these!!!

Planning on using an Intellitronix 5 gauge digital dash which requires analog signals.

I’ve included a link for the Intellitronix gauge.
