I have a DiPricol oil pressure and water temp gauge just sitting in the garage waiting to be installed. My question is do I tap to the OEM oil pressure sending to get a reading? I don’t remember seeing a sending unit in the box. Also where do I install the water temp sensor for my water temp? Appreciate any tips.

 

Which priocol oil psi do you have? They haven't released the optix one yet..

Is the gauge mech or elec?

To install my oil psi gauge, I used a pricol optix 0-100 fuel psi, I tapped into the M10.0x1.0 plug above the ECM.

 

As far as I know they will not be making an electric oil pressure gauge the last I heard. So, its got to be mechanical. I think I would still put an isolator inline to keep the oil outside the cab.

There are also oil pressure ports on the top of the filter head you could use for oil pressure.
There is a 3/8 pipe thread fitting outside the valve cover into the coolant passage on the exhuast side.
