Got to install my ecm today. I wanted to put it inside but i could not due to size of hole i would have to cut to fit harness threw. I put it on pass side fender betwen the batt and coolant resivor. Was the best place i could see to put it that would not get it soaked when i went threw a puddle. Also found out that the factory coolant temp sensor that comes in a lq4 is the same resistance as the one that came with the fast kit so that means no adapters are needed. It even plugs into the fast harness. Only 7 bucks too!
