well depends the einge bay harness is the same but the stuff unde the dash is all diffetn it will not match the rear end wirieng of the car cause the fuse box's changed ever year teh supra was made and still the it has to have the same options as youer car or it will not work and still the some years toyota reused some other there harness and use em in diffetn years so you have to find out what haress is in your car right now
