coolant sensor

Trying to install an aftermarket coolant temp gauge on 2002 4.6l 2v. I think the computer uses the stock sensor on the engine (correct me if I’m wrong), so was looking for an alternate location to install a coolant temp sensor. Any ideas? The sensor that came with the gauge has 1/8” npt...

I’m installing a holley sniper efi on my 83 Ford Mustang; it needs me to use a coolant temp sensor for it. I’d like to keep my oem sensor alive so I don’t have a dead gauge on my dash, is there another spot that I can mount the sensor? Thanks
