Thermometer stopped working after plug change
Hey guys, yesterday change the plugs my self for the first time. I was guided by someone who knew what they were doing. Well everything seemed to be going good, I put NGK V power coppers on, and some O'Reillys wires, but right after the change my thermometer just won't work... While working on the car I notices a write that was not connected anywhere it was hanging right over the manifold, so I am going to try to find where it goes. Also after the change I notice a weird sound coming from the passenger side. Sounds very much like a exhaust leak or a vacuum hose that loose or something. Note I was working being under the car with it being jacked up.

The sensor for the temp gauge in the dash is between the #1 and #3 cylinders on the driver's side.

The metal part of the wire, under that broken plastic cover, slips onto the end of the sensor. The end of the sensor looks like a circle, and the wire slips over it.
