About that cable you were talking about...do you mean the sensor for the outer temperature display??
If so, it should be a (thicker) black cable with a black sensor (4-5cm long) at the front. On european models this sensor is mounted in the front bumper at the left side of the license plate...
hot right fender...just try to sit on the edge of the hood after a long drive...there is a lot of engine-heat underneath the hood that has to be taken care of and this results partly in hot chassis parts. The right fender will be warmer as the left, since the exhaust system is mounted at that side of the engine. The left side is filled with all kind of components and does not get that warm at the fender...
