Can anyone elaborate on the thread in the head?

I'm looking at ordering a gauge and sender, but I don't know if it is metric, or US.

The sender hole in the head should be 3/8" NPT.

It's a U.S. Pipe thread.

i'll insert my mandatory sky is falling post: i wouldnt ever drive again without a functioning gauge or having my autoxray hooked up to monitor temps. i fried an engine when the head gasket blew and kept driving because i didnt know it was overheating

I plan on running the gauge soon but need to replace the ECT sensor now. Would I be safe to assume that, after installing the new sensor and plug, if I just use the two wires for the PCM and leave the 3rd alone I will be fine? Basically like having the 3rd wire dangling free and not connected to anything?... Until I get the gauge hooked up anyways. Rather than getting an ECT for an Impala now then later on buying and replacing a new sensor for the F-Body.

Just for some clarification before someone questions my antics... I am doing some diagnosing with my car right now and that is one of the parts I am going to be changing. I'm not going to be driving it with that wire dangling, I just don't have the new gauges hooked up and want to make sure it's going to be running right.

Just so everyone knows I ran the electric autometer a off the factory sensor but also got a sensor that has 3 wires out a late 90 s10 or blazer jimmy and am using the 3rd wire to run the autometer gauge now so the dash gauge gives me head temp and the autometer gives me the temp in the water pump
