I thought the temp sensor was located above the transmission on the right hand side of the engine just below the lip of the valve cover. I hope the plug is the same, if so, cut the wire and extend it. I know when I replaced mine on my 97 it came with a new sensor and plug with like 2 feet of extra wire. You may want to get a new one as they are pretty inexpensive.
The 95 saturns had two temp sensors and 96+ were OBDII (its smarter and did not need two signals) only requiring one sensor. One for the EGR one for just running. You may have to splice the two lines off of the one sensor.

I just replaced the sensor on my 1998 Saturn SL2.. The temperature sensor/switch is inline with the spark plugs on the drivers side on the engine block and has 2 wires coming from it to the wiring harness. It takes a 13mm deep well socket to remove the sensor. The wires just unplug from the sensor by using a screwdriver to raise the tabs off. simple.
bad fan or bad fan relay
The engine coolant temperature sensor is usually on the front of the engine. The coolant temperature sensor will be in the vicinity of the thermostat housing.
