2006 FORD MUSTANG GT COMPUTER & KEY 4.6 3v AUTOMATIC ECU ECM 6R3A-12A650-XB Both are programmed to match. Has been tested, came from a running car. Please compare the part number and make sure they are compatible with your car. I have also included the VIN # (see pics). I don’t accept returns, so please do not buy this to “try” to see if this fixes your problem. I will only ship to the 48 continental United States. Shipping will be $FREE. We try to keep one of everything in stock for 99-04 and 05-09 Ford Mustang GTs. If there is something in particular that you are looking for, let us know and we will create an auction for you to buy it. Thanks for looking at our ad, but before you go do you know the Lord, Jesus Christ as your Saviour? If not, don't wait until it is eternally too late. You are only one heartbeat away from eternity. Never know when it will be your last. Repent and trust the Lord today as your Saviour.
