Also went to work on the temp adapter and getting the factory gauge to read. I broke the brass adapter I intended to use on the passenger side, so I just decided to go with the three wire FBody sensor in the factory location and tap that into the factory gauge. I know it won’t read in the middle of the gauge but all I need to do is document the temp through the PCM in reference to the gauge location and monitor any increases on the gauge. Install was really straightforward on this. When hot it reads about 1/16” above the cross-hatched portion on the gauge. I didn’t get a good pic of the gauge when it was hot, but did during cool down to show it at least was referencing a temp to the gauge. If I want to I could put a resistor in and move the needle towards the middle, but that’s a big IF.
