factory set up for the temp gauge in the console is that it is an oil temp gauge not a head temp gauge. The oil temp gauge is connected to a sensor in the oil sump/bottom of the engine and is commonly called a taco plate sender (mentioned for searching purposes). The VDO head temp gauge is aftermarket (so no wiring is present in a stock harness) and is a 2 wire item (so you have to run it) with a sensor located under the #3 spark plug (preferred location)
