okay so i replaced the thermostat with one i got from napa....it did not have and hole to be put on the top nor did it have that hole in that flat disc on the back of the washer like the one i took out......so maybe i wont get heat till my engine heats up, which is cool with me im a winter person anyone and i usually keep it at 17C all year round anyway.....but after doing that my temperature gauge isnt reading high up in the red....but its not reading at all..its down at the bottom and wont move after 4 minues of driving( i didnt want to drive any longer on the first run just in case something went wrong :evil: ) anyway so i have this yellow wire that is insulated and comes from under the throttle body and towards the front of the car and i puushed it out of the way so now its up between the plasticbulhead and the throttle body...........is it a yellow wire that shows the temperature gauge on the inside of the car??? if so where does it go cause i cant seem too find anyplace too stick the wire??

please help me out guys

You know, I think the wire for the temperature sensor that runs the gauge was yellow, at least on my '87. It came from where you describe, and was connected to the sensor which was on the battery side of the engine block. Where it connects didn't look like a typical electrical connection. Rather, it looked just like a metal disc that happens to be the right size to accept a 1/4" female spade terminal. I'm not sure if it's the same in 1994, but check it out.
