coolant temp sensor
so i just recently purchased a 1986 4runner with the 22re non turbo with the glorious amount of 275k miles on it. (barely broken in right haha) any way the coolant temp sensor in the top of the thermostat housing has been tampered with and the wire is being held into the plug by house caulking. the sensor on the dash reads above the red line all the time. i have only driven the truck around my neighborhood twice (second time found a mud hole) after fiddling with the wire and or plug to see if it'd change any thing..and it didn't lol. so i went to the auto zone website and the are showing a "2 prong style" (heres the link http://www.autozone.com/autozone/cat...&parentId=52-0 ) yet mine is only a one prong style and only has one wire coming out of the top...am i suppose to have the 2 wire version? i can go take pics if it'll help..
thanks,

so i searched and found a couple threads. (came to the realization i need to go get the haynes book) also is there a way to test the sensor to see if its bad? and so pressumably there is 2 different sensor's under 2 names for the same thing...so you have to coolant temp sensor going to the ecu...but now the second one is just a dummy sensor if you may, that just reads for the gauge on the dash? just trying to make sure i understand the lay out..

I know yours isn't a 90 but it should help give you an idea.
