Temp sensor question; ohms, and thread pitch.

Working on a '07 LQ4. Im trying to figure out if i can just get a temp sensor(same that the comp uses) and put it in the spot on the back of the passenger head and run it to my gauge. So, im wondering if someone has the ohms/temp values handy(to see if they will happen to match my jeep gauge) and i need to know if the threads are the same in both front driver head and the rear of the passenger. I know the passenger rear is a 12x1.5 so is the temp sensor for the comp the same? Any help would be great! And yes i tried and tried searching!

The threads are the same in both heads. Not sure on the ohm range of the sender.
