So the physical oil temperature changes the resistance value? The resistance value changes the output voltage? Your dash reads the output voltage to display a temperature? I never really thought about how these sensors work… ---

Yeah. There is actually a 100 ohm pull up resistor that i soldered into the circuit. ![http://www.race-technology.com/wiki/uploads/HowDoI/1wireSensorDia.gif](http://www.race-technology.com/wiki/uploads/HowDoI/1wireSensorDia.gif) So the dash 2 reads the voltage AFTER the 100 ohm resistor, but BEFORE the sensor. As the sensor changes voltage the voltage between the resistor and the sensor changes. That voltage is run through an algorithm in the dash and output as a temperature reading. Pretty simple. I just bought a 12v power supply though, which i will replace my 5v power supply with, so I can get a bit better resolution… ---

My car runs again! 😃 got the intake all back together, no coolant leaks. I pressure checked it to 20psi and saw nothing, so I feel pretty relieved about that. Tonight I’m going to loom up all the shit in the engine bay and, time permitting, will install the front end… ---

:tup: how much more do you have to do once the front end is on? Small finishing touches? ---
