Ok, first of all, the ecm is programmed to the wrong vehicle. To start with, it has to be flashed with all the correct info from your car. Then the security can be programmed. Have it towed to the dealer and make sure you tell them you installed a used ecm. They may or may not help you. They may want to replace it with a new, which is the right way to do it. I know it is all about the money, but sometimes it is better to do it right without all the hassle.
And, by the way, I hope your issue is the ecm. What were the issues you had that led you to this repair? Hopefully a shop did this diag for you.
