To get the Exhaust gas temp you can do a couple different methods. One is to just put one probe, close to the exhaust port on the manifold this lets you know what one cylinder is doing. Another is to put one probe just after the header goes down to one pipe, this will get an average of what all cylinders are doing. or you can put one on each cylinder so you can see what they are all doing.
