I have a 2005 F150 and bought a Yamaha Water Temperature gauge.<br /><br />The sensor is a brass,threaded bolt with 2 wires that go to the gauge.<br /><br />Can some one tell me which bolt I am supposed to take out of the engine and replace with the sendor/sensor?<br /><br />The wiring installation intructions are very good except all they have is an arrow pointing at the engine block for where the sensor goes.<br /><br />Sure would appeciate any help. Other than where to screw in this sensor, I have everything installed.<br /><br />Thanks
