where to put a sensor, is up to you, what that you want to measure? (ambient air?)
look at new cars see where they put it, ? you'd be amazed at where and why.? and how complex this is (locations are)
lets say you want measure ambient air (out door air) but wait, the car hits 180f temps, easy inside, and even near engine or RAD, or in front top cowling, it gets hot inside any steel box in the sun, and then takes long driving to cool it before that probe reads true ambient air, if EVER.
so how did jeep do that?, answer its in the drivers side mirror. casing , even may have a vent there, to purge hot air fast.
if it gets wet, its not reading ambient air or reads cold wet wind chill factor air, why not just use your cell phone and click on weather underground see temps.?

there is no lack of information there and by GPS location
we have 2 jeeps both with this factory options , not once have we looked at it, (information overload here)
they sell I think a temperature pod to hold this device just for cars, RV boats etc, looks like CELL antenna for cars. just a wand. (drilled to body panels, ouch)
google finds them i think
wires A to B
sure, the car has thing called a firewall, that keeps the burning fuel off passengers. and is part of crush zone for crashing, etc.
on that wall , are rubber grommets. (all cars)
some maybe unused (options) ,some even large, with extra space there to cut a tiny hole for wires in the rubber parts, that is how I do it, not needing to drill holes in the body metal
on the engine side, is best easy way to inventory grommets on the fire wall.
i have an ice pick, i use it to punch a hole in that rubber then ram wires in that hole and it seals up 100% after, tight.
if I had it id use it for accurate coolant water temps, as the stock one stinks in this regard. (to see say a thermostat that is aging and beginning to fail as all do. about 5 to 7 years old.
cheers
