The Mustang Source - Ford Mustang Forums - installed gauges on my 2018 gt

Sure, for the diff. I have a diy diff cooler installed that is fed from the drain plug with 6an fittings. I drained the diff fluid and installed a 6an temp sensor fitting in line coming out of the 1/2"npt to 6an fitting, that is installed directly into the drain and refilled the diff. For the water temp. I installed a inline heater hose (19mm dia.) fitting. I pinched the heater hose on each side of the area I made the cut into the hose. And I also removed about 3/4" of hose so that it would have the same fit after the inline was installed. Make sure you install the inline fitting on the engine to heater core hose. For the trans. I have a PPE alum trans pan that has a sensor port. When I installed the pan I installed the sensor so that I didn't have to deal with it now, (installed over a year ago). Please note that i installed a 1/8NPT jam nut on the fittings before install and installed slip on cramped lug/ground wire so that i can insure i had a good ground to run from the sensor to a grounding source. Then simply attached the sensor wire to the top of the sensor. I should add that I did not disturb the OMG gauges that are in the center instrument cluster. I don't like to use those when I am driving the car at the track because I have to look down to see them. I like all my gauges as close to eye level as possible.
