I'm thinking that if the plug in connections are the same it should be doable IF the message option is available in the ECU or BCM.You probably need to seek assistance from FORD technical supportWhat might it take to swap out a 21 with the massage seats and put them into a 22 model with same trim level obviously with the deleted option? Im hoping the computers are inside the seats and just need to do Forscan option(s) ON. Thoughts??
