Will It Work The Same As Doing The Mustang All I Should Need Is The Harnes And Computer Right
Engine from the 95 and wiring harness from your 5.0L SO should work if you already have a 5.0L,if you have a 3.8L yes you will need the harness and it will need to be repined majorly but can be done.
If you already have a 5.0L just transfer over your accessory brackets and use them not the 95 ones as they differ in position.
95 was a 4.6L.
My brother in law has a 95.......every time I open the hood I see a 4.6........Last year for the 5.0 in an MN-12 was '93.
