    What is this

    This afternoon while I was chaning my turn signal bulbs, i discovered a wire, that looks like it should be plugged in somewhere. Look at the pics below. After thinking about it some more, could this possible be a temperature sensor or thermostat? BTW, i found this under the right headlight assembly

    Re: What is this

    Passanger side correct? That is the temp sensor, there is a hole that it plugs into just under the ballast, I know this because when I replaced my amber turn signal bulbs mine was out too, I pluged it back in, the fit is not tight but it should stay in place, some times taking the headlight assy out pulls it out. You will what looks like a rough drilled hole, just push it back in and it will be fine.
