temp sensors

[Pittman]

Ok we have two one buy the thermostat and one in the water jacket of the head. ( I think thats right, driver side between 3 & 5 )

Which one does the ecm read and which one does the guage read??

Do you guys think there would be any difference between the two at all? Since one is really close to the chamber.

The one next to the thermo is for the ecm and it takes higher readings than the gauge sender
I read yestarday at the speed pro 200*F on a 102*F day and the gauge was at 180* area
This was enough to make me install the stock fan again
