Technically you can use the infotainment ambient air temperature as a digital temperature monitor for something like perhaps the engine oil temperature. Why--The digital gauge is just an indicator/a node device, connected in parallel to the actual ambient temperature probe/sensor. As long as you do not disconnect the electrical wire from the temp probe to the ECM, you might be ok, however, the HDLAN or CANBUS, may throw an error code, so you need to find out the resistance or impedance of the digital monitor and simulate that removed electrical load...kind of like using a load resistor when converting from analog lights to LEDs

However, I am not sure how high the infotainment digital gauge will read in terms of degrees Celsius or Fahrenheit...when sending from the engine motor oil...Another issue is the '13 & below HD oil temp probe resistance may not be correctly calibrated/compatible with the '14 digital readout...I guess the only way to find out is get the HD oil temp probe, connect to the the '14 digital air temp gauge, dip the HD oil probe in a boiling pot of water at "sea level" and see if you get a read out of 100 Celsius or 212 Fahrenheit, and let us all know...

How this helps...

 

You should look at the wiring schematics. You cannot unhook the AAT. It is not connected in parallel. It is wired directly into the BCM & the BCM shares that info with the ECM & the Infotainment system via CANBUS.

 

Yup, quite physically challenging to attempt this, not to mention the complexity of interfacing to the CANBUS. Probably easier to just install a separate temp gauge...thxs

 

Just Go with the Dakota Digital set up it gives you oil temp and a whole lot more : http://www.dakotadigital.com/index.c...rod/prd948.htm

Ah so!
Thx.

 

Ouch, a thousand bucks for a oil temp gauge. DD makes kick a** stuff but not a fan on the displays. I have a set in a 49 pick up but has the proper replica gauge look with modern features. Mike

 

Yup.


WHY, for the life of me I don't understand, does anyone really care about oil temp?

What good is that number?

Nobody has ever had a problem with their oil temp until they install an oil temp gauge, and then it's OMG the SKY is falling....

I don't even think the PV2 reads oil temp anywhere.

Why?

Because it DOESN'T MATTER.
