I'm sorry to say that if the car doesn't have '02 SVT seats, it won't be as simple as re-wiring. Here is a link to an '05 SRS wiring diagram which I'm sure isn't the same as your '02, but it may be of some help: '05 wiring diagrams If you do have '02 seats, each of the plugs from the seat harness is designed to fit only the proper corresponding plug in the main harness. In my '05, all of the individual seat harness plugs are held together in one larger plastic plug which then plugs into a corresponding large plastic plug holding all of the individual plugs from the main harness. The individual plugs will only fit into one spot in the large plastic plug.
In my experience, Focus SRS are model year specific. That is, every SRS component must be from the same model year as the control module located beneath the center console. All SVTs, I believe, came with side seat air bags, so the control module must sense one, with the correct resistance, in each front seat.
I swapped an '03 SVT interior into my '05 ST, and in the process, had to replace the side seat air bags and the front seat belt buckles of the '03 seats, with those from the '05 seats. A further complication for me, though not for you, was that in '05, Ford added a pressure sensor in the passenger side seat cushion which activates those air bags when it senses sufficient weight on that seat.
One last bit of information. The air bag codes can not be read or re-set by the run-of-the-mill OBD2 scanner. A separate program is required, and I have been told that only Ford dealers or qualified independent mechanics/shops can get that program from Ford.
My personal experience is that some dealers will not work on SRS, other than replacing necessary components. Good luck!
