Save your money and don't attach the module, it does not work. It only works during idle and after that the O2 and MAP sensors take over to control the air fuel ratio and timing. Take note that if there is a conflict with the program to your ecm's parameters, your engine will run under limp mode default which would result in less HP and performance. Good luck and if you need ore performance just spend the extra to have your car Dyno Turned.

There are eight COPs (coil-on-plugs) to remove. Using a 7mm or 9/32" socket, remove each bolt securing each COP to the intake manifold on top of the engine. Remove all eight COPs, and the spark plugs are underneath. When replacing the spark plugs, use only the proper Ford/Motorcraft plugs, even if they cost twice as much as the aftermarket ones. You will avoid further headaches this way. Hope this helps.
