All fitted fine mate the  black holder that attaches to the current seat underneath will have to be removed,just slides off and then you detach that black connector box the new seat plugs slot right in, the plugs can only be plugged in one way you will hear a click once done, I had to tie the plugs and the connector box to the underseat with tie grips make sure the seat goes all the way back and forward without putting stain on the wires and that's it, always disconnect the battery,

Hi mate, did you manage to get the heated function working? Thanks

Hi I am about to buy some ecoboost seats to put in my fiesta mk7 zetec would they fit I can see on some of your messages that some of you have had some issues about the little black box would I be able to swap the black box from my old seats and transfer it to my new seats 

Just remember if you can get hold of some lovely ST leather seats for a really cheap price, or a steal as someone above wrote, it's probably because someone is sitting at home in tears with an ST keyfob and V5 and a space where their lovely car once sat........ 

Hi can someone help me as I'm trying to do the same (fit st seats) but I don't want to rip plugs up then plug them all up and my airbags blow out the new seats mines is a 2011 zetec s
