I am planning to swap out the temperature sensor located in the drivers side mirror to see if it helps correct the temperature inaccuracy issues. A friend printed out instructions from the PRODEMAND website and it says to first disconnect the negative battery cable. Can anyone who may have done the swap explain why it’s necessary to disconnect the negative terminal? If I do the swap without disconnecting the negative what would happen? It seems that a quick swap with the truck off shouldn’t affect anything but obviously I’m missing something.
Thanks in advance for your help.
