Default 1998 Mustang V6 to 2003 Mustang V6 Engine Swap

I have a 1998 mustang 3.8 V6 and im going to be swapping in a 2003 3.8 V6
and i was wondering what i would need to do electronics wise. basically when i put in the motor, can i use the same ECU and Wiring harness from the original 98 3.8, or will i have to find a 2003 3.8 ECU and Wiring harness?
