1999 Mustang With 1995 5.0 Swap Ignition Problems

hey guys I'm new here. I gotta problem with my project car. I gotta a 99 which born with a 3.8 pulled it off and installed everything from a 95 gt. When i say everythin,i mean every single wire.
Just when I thought i was done, a little nervous try to started without success... I'm not getting any spark at all. So i started with the basics replaced plugs,wires,coil and just in case the igntion control module but nothing yet :( check all the fuses and they're good.
Anybody has any idea.
