If you add an accessory such as a electric radiator fan with thermal on-off switch, would you splice power wire into fuse box with a fuse tap or into ignition wire under dash to power up system?

Maybe use a Small relay like for a horn or fuel pump with 12v from the battery maybe but fused with an appropriate amp rated (for the fan amp draw) inline fuse & holder. Have the sensor get its source from a switched controlled 12v (fuel solenoid? Radio?) And run it through to trip the relay when cooling is called for by the sensor. Get creative and put a little lights on the dash to monitor constant 12v (green maybe) and maybe a red light wired into the fan power to show when they actually kick on.
