Anyone out there with a 5.0 GT conversion?

Hi, I heard that when a 5.0 Mustang (GT) engine is dropped into a Supercoupe the stock SC wiring harness can be used. Some people I spoke to had problems with the car running on only 7 cylinders when using an H.O ECM. I guess I'm wondering if anyone experienced similar problems and what ECM must be run with such a configuration. Any input will be appreciated..
Thanks.
