does anyone have a wiring diagram or a diagram of all the pins for the ecm. i am looking for the fuel temp sensor pin. i have a fuel temp sensor circut a high voltage code. p0183 and i believe it the problem is one of the pins

C3-48 is the "Low Reference" and C2-27 is the "Fuel Temp sender". Basicly, a loop is made between those pins with the Fuel temp sensor in the middle. C2-27 is yellow, C3-48 is Brown.
if one of these pins where not making a good connection could this potentially cause a p0183 code. sensor high voltage
if the voltage pin was losing connection it would read high voltage. yes. the way it works is the ecm supplies 5 volts to one side of the sensor, and a return line. the voltage that is in the line stays there when the sensor is cold, as the temp heats up the resistance goes down and allows more voltage to pass through the sensor to the referance side.
thanks guys. cougar i am going to try this first and then i will send you my email. thanks again for the help
got it guys it was c3 connector 48. wasnt sure if this was something that would cut the power of the truck or not so i wanted to get it taken care of as fast as possible. i knew i would find it here. thanks again
