The main reason I didn't go more in depth in the write-up is that I don't have a good camera on hand. I only had my phone camera at the time and it doesn't show much detail. I can take any specific pix if you want them though.
I completely deleted the throttle body coolant circuit, I have brass plugs in the rear iron and in the thermostat housing.
When I got my car there was a different water temp gauge sensor already installed in my water filler neck. So there were already threads there and I just used the sensor there at first. I am relocating it to where the stock gauge's sensor is though, which is in the rear iron right under the oil filter. I don't like where it is right now since it is after the thermostat and the warmup temp is probably not the most accurate. Having the sensor in the coolant path actually in the motor is what I want to monitor.
RotaryXperiment I think you're talking about the sensors in the water pump housing. Those temp sensors are for the ECU water temp signal, and for the fan thermoswitch. Seperate from the gauge sensor in the rear iron. After I installed my motor again, I left that sensor unplugged since the stock gauge is next to useless.
