Heck, it saved my first '68 Fairlane one summer day running from Orlando to Daytona and had the car in 2nd vs. drive.

On my phone, I have YouBlue set up to start Torque Pro when the scanner is detected, and Torque has an alert set at 100°C / 212°F coolant temp. This way I have essentially automatic logging & alerts whenever the car is running.

Here is an elegant way to do it, thank you Aonsaithya:

I assume the OBDII port is also dead as I also have a OBDII ELM unit with a built in switch and on/off light. That also shuts off when I lock the car. So I don't see a need to do the above mod. ????
