I wouldn't jump wire any wire going to the computer. Its to sensitive and a minor voltage spike could destroy it. I would buy a manual with wiring diagrams for the mustang.

check all grounds even to the computer.....all the wires on your ignition module right???? if i'm not mistaken the computer only draws 5v????so i wouldn't do it.
