3 Wire Camaro Coolant Temp Sensor Resistor.

I haven't seen a definitive answer for that question, most people either live with it being off, or they use the stock sensor installed in the engine in another location (which is what I did). I had the stock sensor (a few of them) turned down on the lathe and threaded to fit on the passenger rear head and just used my stock wiring to the gauge.

I just noticed that my 92 k1500 with 6.0 swap reads about 20 degrees cooler than the actual coolant temp is. Is that due to the adapter taking the stock sensor out of the direct line of the coolant?

That's not a bad idea using the potentiometer, I'm definitely gonna have to try that. I have the 3 wire camaro gauge and I'm pretty sure I'm reading about 10-15 degrees off but I'll have to check reading in the ecm vs the gauge
