Default 1994 G20 coolant sensor

Hi to all. I am new to the forum and from Trout Run, Pa. I am having problems finding a sensor for my 1994 Chevy G20. It has a 5.0 in it. My temperature gauge doesn’t work, and I took a sensor out that go’s in the intake near the throttle body. Went to Advance, they gave me a Coolant Temperature Sensor. It is not right. I checked their web sight, but can not find the sensor that I removed. All the sensors I have found have a rectangular base where as mine has a round base, with fine blade male prongs. Any Help?
Thanks, Ken
I think I found the Temp sensor. Drivers side, middle of the block. Still don't know what the other sensor is, also it is located in the front of the intake.

I think the sensor on the intake may be for the TBI. I will know today. I ordered both sensors from my local General Motors Dealer. Advance Auto gave me the wrong Temp. Sensor twice now. The only thing is the price went from $11.00 each to $33.00 each. I am taking both of the old ones with me, to make sure I get the right ones.
Thanks

Your question about: Engine Coolant Temperature Sensor has been answered.
On 01/19/2011 you asked the following question at Advance Auto Parts
"I have a 1994 Chevy G20 with a 5.0. I bought a WT3000Z Coolant Temperature Sensor from my local Advance Auto because my Temperature gauge is not working. I believe I have located the sensor, drivers side around the center of the block. The sensor on the truck looks bigger than the one I purchase. Do I have the correct sensor or do I need the 213-77? Also, there is a sensor located on the front of the intake, passenger side. I can not find this sensor, and am not sure what it controls. I want to replace it. It has a round base, where as the temp sensors I see all have a rectangle base. Any help? Thanks, Ken"
Chevy Expert from edmonton ky said:
"you have the sensor for the top on the intake i to just recentl bought this sensor for the same reason i put it in and it didnt work this is the same sensor as the wt300z what you need is the wt3025. what these two sensors do is one reads the temperature at the top of the motor and the one on the side of the motor reads it down ther the snsor with 2 terminals is the one on top and one wire runs to this other sensor it like cross checking to make sure its getting an accurate reading then the other wire goes to the gauge."
