04+ Where is the sensor for the Temp displayed on the HUD?

On my 05' the HUD always displays the temp as 105*, 146*, 176*, 94* and every once in a blue moon, about the correct temperature. I have checked and found a temp sensor in the bumper cover and changed it to no real effect. I have followed the wires as far as I can and haven't found any breaks and have lost it back into a larger loom on the Passenger side. Bobba got me a schematic of the HUD, but there were missing pages I think as he had told me before hand they were pretty worthless. The thing that gets me is that if I read Ambient Temp through Torque Pro it is correct. Does anyone have a complete Schematic for the 05'?

Thanks,

Jeff
 


Hmm I wonder where next then. BTW if it was using the MAF IAT then mine were going to be sky high. I have he MAF out of the heat of the engine compartment now and my IAT's are much closer to ambient like this morning my IAT's were about 65-80, but the HUD still says 105*. Before my IAT's would be in the 140-170 range.
