You are right sir!. Actually, i'm making progress today. I went to the junk yard and found a lumina w/that green wire, which i took. Now, here's the funny part----The green wire on the harness that is supposed to go to the sensor on the back head was spliced with the white wire coming off the TPS---i cut that wire, reconnected the green with the one on the back head, and the fans shut off, and the temp gauge works....one problem solved. However, the idle is still high, and i have no idea where the white wire from the TOS(wire "C" as the manual calls it.) Now, all i have to do is connect the white wire where ever it is supposed to go, and i'm guessing that should take care of it.....Now, to find the white wire's home..........
