I carried this out on my V12 S and went from the sports seats to the lightweight seats. Mechanically and electrically it is a direct swap - unbolt the seat frames from the car, disconnect the wiring and seat belt mount and remove from the car. Replace with the other seat. The car will now need connecting to AMDS to programme the vehicle SRS RCM modules to either let it know there are no seat airbags as per lightweight seat or let it know it has seat airbags now as per sports seat.

As an aside, the dash side buttons to move the lightweight seats forward for access to rear will be redundant on the sports seats, and the car that gets the lightweight seats might want to think about fitting these.

Feel free to PM for further any further details.

Forgot to add, it could be possible to add resistors across the airbag circuits to get the RCM to think that there are still airbags in the car where the sports seats have come from. Not sure if this will effect your insurance or effectiveness of other airbags should they ever need to deploy, conversely the car that had lightweight seats never had the airbags in the seats that would now be in it.

Did you recode yours rather than use a resistor?

Yes I had access to AMDS to recode my car properly. It was literally about 15mins work to install files. As I used the same seat ECU’s, these too had to be programmed to know that they were now on lightweight seats. As you are swapping complete seats and ECU’s you won’t need to reprogram these. I’m not a fan of putting a resistor in the airbag circuit when there is a factory/correct way of carrying it out as per official option.

Slightly off topic...

What dash side buttons?

I think he meant seat side buttons, maybe?

Button on the side of the dash to move the lightweight seats all the way forward

Those seats look great. Did you have them retrimmed to match the colour or did you order them from Aston Martin like that?

I ordered new seats from AM. They come trimmed to your specification/requirements. I went for the original style as per the sales brochures.

Two Indys reckon it takes a whole day to swap the seats and do the coding. I think they are taking the p@@@. The seats have four bolts and (presumably) a couple of electrical plugs. Plus each car will require a short time recoding the cars. How can this be a days work?

It's a horrible, time consuming job

Has anyone fitted these ECPS bucket seats in their Aston? They look pretty close to the factory ones. Any pictures to share? Please
