Default Permanent Disable of Inteligent Start/Stop

Hello! Does anyone know which exact plug to disconnect to permanently disable the start/stop on a 2020 RR P400?

Thank you very much!

ours was programmed when we bought it used, and the programming was wiped when i changed the battery. i am just waiting for the starter to go our because of the constant stop and start. i know you can code it, i just cant find anybody here in AZ who will do it for less than 300$

For anyone finding this old thread, there is no need for a "permanent" disabling because you can simply assign the CCF to just stay as it was left during previous operation. Meaning, engage the button to turn the stop/start off, and the next time you come back to start the engine, it will still be like that, off.
We use the GAP iidtool to do this. It works on my RR as well as on new Defenders.

There is a long thread on here in the 2020 defender section about GAP tool codes and things to customize.
