AT some point an aging Automotive Wireharness will be soldered on. I prefer to not have a solder joint in a high flex location, like at the ends..
The temp sensor is not critical.. it's part of the Hot Start Scheme.. I've removed the 'Hot Start PRV Sol from my '90 Daily Driver.. just to clean up the Sol and lines on the Left Side of the Plenum..
You can solder in a dummy load resistor in the Wireharness to keep the ECU from tossing a code about the sensor being missing..
