    I may be wrong but you shouldn't need them. They are for the mod cars that have two sets. They are used when you need to trick/fool the puter into thinking they are working when u remove or add high flow cats instead of the factory set up. I am not sure on why they would be used on a 5.0.


    Anyone I am lost here.

    Yes you could remove the check engine light, but that would be a major bandaid and not fix the real problem. The idea (as I understand it) of mil's is to fool the computer into thinking that you still have cats on a car that really doesn't have them. Since a fox doesn't have an o2 behind the second set of cats you can remove them with no real effects on your computers performance.

    The rear set of a o2's simply transmit a signal to the computer, it the signal is in range the computer does nothing, when u omit the cats the exhaust isn't superheated (as the purposte of cats is the heat the exhaust to burn off excess fuel) then the o2's get a different reading and flip the cel. By creating mil's you trick the computer into thinking the rear set is up to par or within the correct range at all times.
