The oem position is extremely hard to get to unless you have a lift, I though there might be a top side area I could get an accurate temp reading. Plus I can never actually get the info of what the oem position is, I know generally where it is located. I know it has a temp sensor unit and a temp sender unit, one goes to the ECM the other to the gauge cluster itself, but I'm not sure which is which. Does anyone know what the wire looks like coming out of the unit I need to replace with the aftermarket temp sensor?
