Do the 2.4's have a temperature switch? i see 3 going into the thermostat housing, but it seems they are all "sensors" and not open/closed switches. I plan on hard wiring on a key hot until i figure it out. Just didn't want to add more switches/sensors if i don't need to. Any help is appreciated

1. Does anyone know if i can tap any of these to for an open/closed circuit?
2. What are all these for? (i figured one is for the gauge and another for the computer, not sure what the 3rd is for...
3. Is there a wire in the computer i can use as a source?
