The right answer is much better than several opinions.
Those who have been around awhile know this question has been answered many, many times, and always in the same way. So, a

would produce the same answer scamaro355 provided, and many times over.
Another way to look at it is if scamaro355 had provided erroneous information, someone would have chimed in.
Not trying to bust you or discourage you from posting/asking questions, just trying to explain how things tend to work here.
(To contradict myself slightly, the only thing scamaro355 could have added is you need to disconnect the harness from the ECM before you can pull the harness out through the fenderwell. But, if you couldn't figure that out when you got to that point, you're way over your head on this project, anyway.)
