I did it... 2002 SVT seats in my 2005 zx5 SES. I swaped the pigtail of the 2005 seats to the 2002 ones. Swaped the belt lock and sluts and swaped the gel pad from the passenger seat of the 2005 in the 2002 seat. No airbag light, (ABS-Traction) control works and everything is fine
note : I don't have standart side airbags so I don't know if it's gonna work well.
Took 3 hours with a friend who works in a Ford dealer. (taking the seats out of the car + work with the wire plugs swap + airbag gel sensor swap + put it back in the Foci)
Best upgrade I did to my car
