2023 Triumph Scrambler 1200xe Ecu Location

Did you ever get a straight answer.. I am trying to do the same on a 2023 1200 EX. There us no way it behind the battery box like some say without taking alot of parts off

 

I have only just seen your post as I have been absent from the forum for a while. You need to remove your seat and the ECU cable connector is in front of the fuse box behind the petrol tank. To access the ECU you need to remove the tank, it is located behind the airbox.
