I did it, Swap 2002 SVT leather seats with red inserts in my 2005 zx5. Had to switch the plugs and the passenger air bag sensor. BUT you have a 2000 zx3 so you don't have the air bag sensor in the passenger seat and I think your plugs will be plug and play.. But not shure .
My heated seat plug dont work because the two harnest are different (from 00/04 to 05/07).
Fot the rest, it,s bolt on and easy to swap them !
